I actually have Ice Queen planned for the future, but my gf is still deciding what she'll cosplay when I do, since I'm also planning a possible Prince Gumball as well. Got really excited for cosplay when the character sheets came out, and now we get to see a preview of the ep! We flipped out at all the new costumes for Marceline, thanks to Memory of a Memory! It'd be so cute if someone did little Bubblegum and little Marceline!
Are some of you guys still planning AT for Otakon? I'll be Bubblegum in her Trouble in Lumpy Space outfit, and my gf is Marceline in her Heat Signature outfit.
