The puzzle reads: "Here's a little paper goldfish. You can make the goldfish into a triangle by cutting carefully along the dots to make two pieces, then rotating the resulting pieces to put them together. Where should you cut it? Draw lines with the stylus across only the places where you should cut." The objective bar says "Make the fish a triangle!"

The top screen shows the goldfish, an arrow and the triangle it should become. The goldfish has a forked tail fin with a triangular notch cut into it. On the touch screen, the same goldfish sits on a grid of small orange dots. You draw short straight lines from dot to dot to mark the cuts, then touch Submit. You don't move the pieces yourself.

Wrong Puzzle 109?

  • Daily Puzzle 109 is Ducks 05, from the Little Lost Ducklings set.
  • Puzzle 108, Balls and Boxes, is the puzzle before this one, in Carnival Arcade. If yours has a row of numbered boxes and a ball, that's the one you've got.
  • Puzzle 110, Cozy Cabins, is the next puzzle, also in Knickknack Alley. If yours is about a family of five and four cabins, that's the one you've got.
  • Puzzle 109 in another Layton game is a different puzzle. If yours doesn't show a paper goldfish, you're in the wrong game.

Where you find it

Chapter 7 opens on the fourth day of the investigation in Monte d'Or. Go to Knickknack Alley, the narrow street of shops, and talk to Guy behind the counter of his toy stall on the right. He's there for all of Chapter 7.

Guy greets Emmy: "Why, hello there, Emmy. How are you? May I get you something? Anything? Everything?" Emmy asks, "You haven't learned anything about the Masked Gentleman, have you?" and Guy admits, "Sadly, I have not. I'm sorry. So sorry." As she turns to go, he calls, "Wait, don't go! Try solving this puzzle! It will help your investigation!" and the puzzle starts.

Knickknack Alley: a narrow street of shops with a toy stall on the right, a burly stallholder in its window among stuffed toys, a toy car and cart on the ground in front, a gold ring around the stall window with a plate reading Guy, Puzzle 109, three numbered hint-coin markers at an upper-left window, on the stall counter and on the stall's roof bracket, and a ring marked Zoom on the wall to the right of the stall
Illustration of Knickknack Alley. The gold ring marks Guy; the numbers mark three hint coins, and Zoom marks the spot with three more.

Knickknack Alley has six hint coins. Three are in the normal view: in the upper-left window, in the red bucket and on the decoration on a shop roof. The other three, in the window at the top center, in a container and on the neon sign, are in the zoomed-in view, so zoom in to find them.

Each coin can be collected only once. These are the same six coins as on your earlier visits for puzzles such as Puzzle 005 and Puzzle 033, so if you tapped them then, they're already gone.

You don't have to solve it to move on. Guy keeps offering it for the rest of Chapter 7 and after the story ends.

When the goldfish won't become a triangle

  • You cut straight through the fins. That makes three pieces, as Hint 2 points out. The answer has to leave exactly two.
  • You don't know where to start. Look at the triangular notch in the tail fin. Hints 1 and 2 are about what it tells you.
  • The game says "Too bad." The wrong-answer message is "Too bad. You only need to cut it into two pieces, remember." Check that your cuts make exactly two pieces, and that you didn't draw any extra lines.
  • You can't find the puzzle. Talk to Guy at the toy stall in Knickknack Alley any time in Chapter 7.

Hints, one at a time

These are the game's own hints, word for word from the North American version and in the same order. Open only the next one you need. In the game, Hints 1 to 3 cost one hint coin each and the Super Hint costs two.

Hint 1: the tail fin

Are there any parts that'll help you get started?

There's a triangular indentation in the tail fin of the goldfish. What does that tell you?

If only you could cut the goldfish into three-- then you could simply cut straight through the fins.

Hint 2: two pieces only

If you cut through the fins, you'll end up with three pieces, so that's a nonstarter.

You've got to deal with the indentation in the tail fin, though. Try cutting out the shape of the indentation somewhere else, then using that shape to fill in the gap.

Hint 3: the first cut

Did you work out where you need to cut in order to create a shape that'll fill in the gap?

Find the dot second from the right, third from the top, then make a small cut going upward and to the left.

When this cut is paired with the fish's side, it makes a triangular point that would fit nicely into the gap in the tail.

Super Hint: the rest of the cuts

After cutting the fish as described in Hint 3, make another small cut going downward and to the left.

Can you see where you're going with this?

Next, you just need to cut downward and to the right!

Answer and full solution

The answer below gives all four short cuts in order and shows the finished triangle. Open it when you're ready.

Show the answer

Answer: draw four short cuts in a zigzag across the back of the body, from the top of the tail fin to the bottom of it: up and to the left, down and to the left, down and to the right, and down and to the right again. That splits the goldfish into two pieces that fit together as a triangle.

Step by step:

  1. Start at the dot second from the right, third from the top, where the top of the tail fin meets the body. Draw a short line up and to the left, to the next dot.
  2. From there, draw a short line down and to the left, to the dot just behind the eye.
  3. From the dot behind the eye, draw a short line down and to the right, to the next dot.
  4. Carry on down and to the right to the dot where the bottom of the tail fin meets the body. Then touch Submit.

Illustration of the four cuts, numbered in the order the hints give them.

The first cut, together with the edge of the fish's back, makes the triangular point that Hint 3 describes. When the pieces are turned around, that point fills the notch in the tail, and the two pieces make the triangle.

The finished puzzle: on the top screen, the goldfish split into a light piece and a dark piece, an arrow, and the two pieces fitted together as a triangle, with the child swimming in a snorkel mask below; on the touch screen, the goldfish with the four yellow cut lines drawn across its body
Illustration of the cuts on the touch screen, and the two pieces fitted together as a triangle on the top screen.

The game confirms it: "Gold on you! If all goldfish could turn into triangles, they'd have far fewer natural predators!"

If it still doesn't work out:

  • You started at the wrong dot. The first cut starts where the top of the tail fin meets the body, at the dot Hint 3 describes, and runs up and to the left.
  • Your zigzag stops short. All four lines are needed. The cut has to run from the top of the tail fin to the bottom of it, or the fish stays in one piece.

Picarats, hints and hint coins

Fishy Triangle shows 45 picarats when it starts. The puzzle can award 45, 41 or 36 picarats. Wrong answers may reduce the picarat value. A wrong answer brings the message "Too bad. You only need to cut it into two pieces, remember." If you quit, Guy says, "If you can solve it, the answer may help your investigation." When you come back to try again, he says, "Emmy, please try to solve this puzzle before you go anywhere else."

Hints cost hint coins, not picarats. Hints 1 to 3 cost one hint coin each and the Super Hint costs two, five in total. Knickknack Alley's six coins are enough for all four hints if you haven't collected them yet. The hints on this page are free to open.

Does it unlock anything?

It doesn't give you an item. You get the picarats, and the puzzle counts toward your total.

Versions

  • Nintendo 3DS family: this page covers the 3DS game. The goldfish and the target triangle are on the top screen, and you draw the cuts on the touch screen.
  • US and UK English versions: same goldfish, same answer and the same name. The UK question and hints differ only in small details of wording, and the toy-stall owner is called Jean-Paul.

The scene around the puzzle

When it's solved, Guy says, "My goodness. I knew you could do it!" Emmy asks, "How did that puzzle help my investigation?"

Guy owns up: "Oh, uh...I thought maybe there was a connection. Oops! Heh heh. I'm sorry! I just couldn't bear to watch you go!" Emmy answers, "Oh, right. Thanks a lot, Guy."
