I don't think C3P0 is much of a swimmer, guessing by the expression on his face. I do, however delight at the idea of a parallel "Star Wars" in a Mario-style underwater level.
Can't you see this cake inspiring an entire room's worth of decor? I like kids decor that can transition through the years. I feel like pink and blue are such baby colors that don't apply quite so well when they become toddlers. Green and yellow are always classic.
What a lump of cuteness! Slap a kawaii face on an amorphous blob and I'll melt. I'm such a softie. Honestly, this could be a marshmallow, just a cylinder of puffy sugar, and I would still coo over it. Also, I think this cake would be an adorable hat. It would have to be about 4 inches across and have a pretty ribbon to tie it on. I'd wear it every day.
