All who have seen the movie knows what the beast looks like.
Combat:
A space monkey would rather run and hide than fight, mostly due to the fact that it's allmost exclusevely a herbivore. Camouflage (ex): The space monkey has an inate color changing ability similar to, but much more powerful than that of a chameleon, giving it an inate +10 bonus on hide checks, it can quite litterally dissapear before your eyes. Skills: A space moneky gets a +4 racial bonus on all listen, search and spot checks.
actually, it DID grow up to be a big strong Yeti thing.
But maybe that footage was only on the DVD's Deleted Scenes portion.
Either way, that was the full intent of the filmmakers was to have Blarp grow up to be rather big and strong.
