"Haha!" Baby throws a little pretend punch. "Other guy go BOOM!" So it seems he got your joke!?!

"Mirror, yeah," Baby answers, nodding. He pap pap paps a nearby mirror. "Baby fall out! Not-a bad, for a baby. No ouchie."

After communicating this, the baby frowns very seriously at Thancred. And then all of a sudden he starts rummaging in his pocket... hang on... no that's a cracker... ball for funny... maybe he can play ball later!!! ....here it is!

Baby Mario produces a mushroom from his pocket, red with white spots, friendly looking, if comically so. He shoves it into Thancred's face. "Eat up! Ouchie feel better!"
