The build is pretty good, you can definitely tell that it's Pocoyo. I think it'd be nice if you rounded out the bottom a bit though, instead of it just being a rectangle.
The theme is original, no Pocoyo maps to my knowledge.
The parkour is fun, varied, and suitably long/difficult for a medium. There are a few harder jumps though, like the fence to wall jump near the end, so you may want to slightly nerf them.
Overall, a very enjoyable map. +1, good job and good luck!
