Soda with the same new toy:
It's like having a junior Godzilla as a cat.
and he's like this for everything. When Pony makes biscuits? He's all, *knead* *knead* *knead*. When Soda makes biscuits? He starts out with *knead* *knead* *knead*, and then he's digging to China, and pretty soon he's got his back legs churning, and it's just about then that he explodes and goes tearing off into another room as fast as he can run. It's like total-body-workout-biscuit-making.
He's just ... exuberant. Or crazy. Either one.
