Gideon and "giddy" may have been a coincidence. Fun fact: Gideon is the hebrew word for "feller of trees" or "lumberjack", his mortal enemies hapeneing to have the last name of a tree. It could be that they names him Gleeful after realizing his name sounded like Giddy though.

Honestly, I'm unsure. I think both sides here are going too far with the arguments. I agree, it does sound a little far fetched, but we just as we can't prove it's canon, we can't prove it's not either. Althought, I doubt the Dipper one simply because it has Llama in it. Wendy's middle name I'll gladly take as Blerble until we learn otherwise :D
