Boop is a very simple little guy, doesn't have much going on up in the ol' noggin' and that's perfectly fine by zem.
The purple pacapillar is always happy to spend time with his friends, and tries to be helpful whenever zey can, but due to their clumsiness usually end up being more of a mild bother than anything else. They're skilled in other ways though, being surprisingly knowledgable on gardening and linguistics of all things... maybe they do have some more than two braincells up there after all, even if those cells only work for specific topics.
