im at the part in the planitarium where there is this pink creature and i dont know what to do to get rid of it or if i even have to and if not what im supposed to do.!?

Okay. Well, this was the hardest level so far for me(haven't beaten the game yet, only on Hotfoot Springs).

Those pink things are the Power Parasites JB was talking about.

Ignore it for now, but those things become the biggest pains in the entire game soon.

Eventually, you'll have to shoot all the gunk off one of the rotating orby things. That thing will repeatedly appear, no matter how much you try to shoot it with the cannon. If you don't get rid of it, it will gunk up the place, making your life VERY, VERY DIFFICULT. God I hate those things...

So you can kill them with either your Thwark(not sure if you can kill them with Bolas) or one of JB's cannons.

You will come to hate them, trust me.
