Old game can’t remember it

A long time ago I remember playing a game on my grandpa’s computer when they were running on dialup internet and I can’t remember the games name at all. All I remember er about it was the main character was a goofy purple alien that was shaped kinda like a “!” And the hand and feet weren’t connected to the body. And the guy somehow lost some kind of drink or potion or whatever that fell down to the planet below and started changing everything and after he crashed had to go and try to get it back or fix everything. Sorry for the long post but please of anyone remembers this I’m dying to know what it is! Especially if you have pictures about it because I can’t find it online when I looked!
