This hedgehog and his hamster pals are Team Tiny Cake (not to be confused with cupcake).
Further description from our intrepid tipster:
My niece and nephew are going insane for this.
Tiny Birthday for a Tiny Hedgehog. It's got cake. It's got party hats. And honest to Jesus, it might actually be better than the first video of Hamsters eating burritos! Life as we know it has changed irrevocably.
But don't take his word for it; see for yourself!
