Smiling Pets AU Idea:

So, a thought, what if Mr. Boss was like a type of monkey. (proboscis possibly)

Charlie would be like a chilled out pig, not a hog, a pig, totally different.

Glep would be like a rodent of some sort. (maybe a hamster? haven't figured that out yet. don't even know what glep is.)

Pim would be like a badger or something?

Finally for alan, probably like a reptile-ish, scaly, type of animal. Just a thought.
