Sure, you could wrestle your toddler into a scratchy costume with too many straps and confusing headpieces… or you could zip them into this Blue Monster Onesie, watch them instantly transform into a grinning Sully, a bubbly Mino, or a zippy little Piku, and call it a win for everyone. Bonus: they’ll probably want to wear it to bed.
