When I was a child I had a board game that featured small plastic monsters. If I recall each player chose a type of monster and you got three monsters to play with of that type.
I remember nothing of the game play apart from I that I think you could chose which of your monsters you moved in your turn.
There were Blue, Yellow, Red and Green Monsters I remember the Blue monsters where like lumpy blue clouds on legs with a bulbous nose and one of the other colours was triangle shaped with an eye on two of the three sides of the triangles.
A friend asked me what the game was called recently and though I remember playing it I can't for the life of me remember what it was called.
