In which I officially admit to being a creepy Sloth-stalker, and to his face no less: [link]
Extensive research went into this page. As it turns out Neopia has a smörgåsbord of wild and weird beverages, so yes, space spice, tigersquash, kabuggle mocha, sourmelon brew and amaretto biscuits can all be found on Neopets.
I think Sloth would actually be fine with having an obsessed fangirl around. He's full of himself that way. Also, what do you picture his voice sounding like? In my head it keeps turning into James Earl Jones every so often.
I haven't found a match for what I think would suit his voice, and I've been a fan of his for years. However, there are several audio clips of him laughing in various games on Neopets, and they lower the pitch so it's freakishly low. I guess James Earl Jones isn't such a long shot, especially since he also did the voice of another inter-galactic villain.
