Ammy is tracking down stray dinosaurs, and, since the zoo is one of the few places that smell like a lot of animals live there, she figures that some of them must have been lured by that.

Discovering Son Gokuu as well as a flock of hungry raptors isn't quite what she expected, admittedly. Gossip flies swiftly between Heavens, but the last Amaterasu heard, he was trapped under Buddha's hand made stone.

...and of course he's fighting the raptors before trying to herd them. Amaterasu isn't angry, Son Gokuu. Just disappointed. She barks, loud enough to be heard over the fighting.
