Grandpa : Alright, Samuel!
Rocky : Sir!

Rocky : [Receives mask] Awesome! Yeah!
Grandpa : Ahh, Jeffrey. Fast and free, spirit of the young wild horse; you shall be known as Colt!
Colt : Colt? That's cool.
Tum Tum : What about me? Can I be Monster Destroyer? Or how about Super Killer?
Colt : How about Super Dork?
Tum Tum : Shut up, spazz!
Grandpa : Ah, little one. Since your energy begins and ends with your tummy; you shall be known as Tum Tum!
Tum Tum : Tum Tum!
[Both Tum Tum and Grandpa laugh]
Colt : I can't wait 'till we show these to dad!
Rocky : He'll hate 'em.
