The last of the Kinder Maxi 2023 penguin figure series is this small dood who has gone fishing. The log the penguin sits on works as a seesaw mechanism, making the penguin pull the rod. The block the fish is in comes with a small frame that allows it to 'float' up-and-down, following the movement. I left the frame out as it looks better in a photo that way.
