What should I name my little blue troll character?

He's a website mascot, is small, blue and furry, long ears and a cute little character. Personality is like that of an average ten year old boy, somewhat mischevious. I'm trying to stay away from names that end in "y" or "ie" such as Brimsley or something like that, it just sounds corny to me. His partner's name is Grimm so it should go well with that. Here are some I've thought of....Burwood, Trigger, Baxter, Cobalt, Tizzo, Widget, Bogart, Rascal, Bugbear, Tomtar, Rockwell, Jasper, Bugster, Hatch, Leo, Ringo, Elvis, Sherwood, Archer, Barlow, Jagger...and there are many more, however, the ones I like the most are fairly ordinary...Max, Maxx, or a version of it, Maxwell, Maxter, Axel, or the only "ey" name I like, Ripley or Ridley. Originally it was Buster but there are too many popular "Busters" out there. So of all those names mentioned which one should I pick? Or if you know of a unique name that is "tough" yet "lighthearted", let me know. Thanks!
