I'll start with my favorite show first.
I've been enjoying most of the episodes especially when certain background characters return.
My favorite character so far is a tie between Dave the intern capybara and Comedy Chimp.
Is it just me or does Comedy Chimp sound like Rick from Rick and Morty?
I don't have a favorite episode because there's too many but I can say Knuckles is definitely the funniest character in the show. (I still find the scene with him destroying the compass to be the funniest!)
Now on to MLP FiM!
Meh... I've been more hyped and focused on watching Sonic Boom but I can say that this scene really caught my attention in the newest episode.
I forgot to mention that Make new friends but keep Discord is my favorite season 5 episode so far and I hope that he does silly things like he did in future episodes.
