Uhhhh, he jumped somewhere. Toph has no idea where - he's too small and it happened too fast. But even so, she's totally and completely unafraid of him - just pissed. When he lands on her shoulder she jolts from surprise, not from fear of harm.

Still scowling angrily, she cups her hands and tries to grab him as if he were a lizard in her family's garden. What a pest.
