[He has grown to an enormous size, and has defeated Dragon's children] Giant Tommy's coming to save you, Taffy! [he suddenly shrinks back to his normal size] Uh, regular-sized Tommy's still coming to save you, Taffy! [He runs towards Taffy, but Dragon drops an egg on him, causing him to shrink down to the size of a mouse. Kimi runs towards him. in a high-pitched voice] Uh, really really small Tommy thinks he should probably run by now!

Kimi

I got you, teeny-tiny Tommy! [She picks up Tommy, and as she runs away with him, Tommy grows back to his normal size, causing Kimi to fall over]
