well I can tell you my frog was named because people said he was butt ugly and when he sings at night it sounds like he is singing his name { my name is Bud Ugly, Bud Ugly, Bud Ugly}
suggestions: Mr. Hopper - Mr Jiggles- Fredrick the Frog -

I also have land hermit crabs, I wait to see what their personalities are before I name them, Crabby Paddy { a big bully and male }- Shell Lee very long slendar delicate looking also a male- Slater, love to scale and climb the slate rock I have in the tank, male- Pebbles, came in a shell looked like a rock, Female? in iso right now- Digger, likes to dig around. something you might want to do is wait ans see if they do anything special
