What the name of this PC game?

Hi!

Basically I'm feeling very nostalgic today and I kept remembering playing a game at school, but I can't remember the name of the game.

We used to play this game in Junior school (back in 1998-2002)...

I can't remember what game was about what I can kind of remember what it looks like.

You play as a group of Purple things, each level you have to solve a puzzle, for example first level was trying to survive going across a broken bridge. You choose one the Purple things, like one with a spring bottom or one with a flying hat and try to keep them from falling off the bridge. Another level was trying to go across a pond by landing on leaves. The objective of the game was to keep as many as possible or they all die and game over.

I know it's not much info but I so badly want to play this game and will be forever grateful to you =)
