The Softest Thing He Owns
Ordered the Squirtle for my son's first Halloween and it ended up being his everyday outfit. The fleece is unbelievably soft and the little shell on the back kills me every time. Already eyeing the Gengar for his cousin.

The Whole Family Matched
We got the Snorlax for our baby girl and she looked so cute we had to get matching ones for us. Dad's in the Charmander and I'm wearing Eevee. We get compliments every time we post a photo. The quality is the same across all three sizes, genuinely impressed.
If they don't love it, we'll refund you. Simple as that.
We know buying online for your little one takes trust. That's why every order ships free, worldwide, and comes with a full 30-day money-back guarantee.
