Colorful puzzle platform game?
 

I remember a game in the 90's that was made for DOS I believe. It was a colorful platformer puzzle where you would walk around to solve fun puzzles in a "fun factory" environment.

Think of "The Incredible Machine" except that all the pieces are already placed on the screen and you have to push them around to solve the puzzle.

I don't remember what the goal of each level was but I'll list what else I remember:

-You controlled a short blue or purple round creature
-Tile-based levels
-You can push blocks out of the way
-You can climb up ladders
-It was a demo, but showed some of the fun things it had in the full version
-There were fans that blew objects away from them
-Pipes to transport objects through them
-Ice blocks to slide them across
-^ They used the above three to make a perpetual loop of moving objects, it was fun to watch^
-Balloons could lift blocks
-Springs that would push blocks up or wherever
-Magnets to attract stuff
-Conveyor Belts?
-Fires? & Long strings for the fire to travel through

I don't know the game you are talking about but you might like
Subterra at Abandonia Reloaded;)

Though you have to put pieces yourself could it be Sid & AL's Incredible Toons?
