In Carto, there is a Trophy called Strange Catch, which asks you to “Find something mysterious in the lake.” This one’s pretty sneaky, so here’s a complete guide to getting the Strange Catch Trophy.
This one is actually found in Chapter 8. Once you talk to everyone on the island, there will be a fishing tournament. You need to win the tournament to get the grand prize: the ocean map.
In order to win the tournament, you’ll need to catch four types of fish. Each fish is based on one of the child’s drawings, shown below.
The idea is to rearrange the lake tile pieces to create each fish. Once you do, you’ll be able to catch a fish of that type.
But there’s a sneaky fifth fish that has also been drawn for you. You just need to look at the ground where the child is scratching at the ground with a stick.
Now just make that lake shape, like this:
If you fish in this lake, you will catch “something mysterious” and pop the Trophy. This will also earn you Secret Piece I (you can earn additional pieces of this puzzle by getting more of the game’s Trophies).
And that’s how you earn the Strange Catch Trophy in Carto!
