Someone already thought of the concept before I did!
So anyway, looks like some loser on YouTube has a BumbleBear channel, and they have no talent, 50 subs and around 250 views. I would have preferred that, if someone beats me to the punch, they would have actually done something with it. Oh wells.There's also a BumbleBear children's book, which is almost as horrid.
Grumble Bee is a stupid Power Rangers Boss.
So I might go with "Grumble Bear".
