What are three clues who the bomber is?

1) “Hurry up, Angela, you’re such a poke,” Turtle complained. Suddenly there she was, kneeling down to peek
under the lid.

2) The captain would not call them bombs. “More like childish pranks,” he said.
(Childish pranks! That brat’s capable of anything.)

3)“Don’t worry, you’ll still be pretty,” Turtle said. “But, wow, that sure was a dumb thing to do.”
Sydelle Pulaski’s eyes popped open in surprise. Quickly she squeezed them shut and uttered another loud snore. Well,
what do you know? Her sweet, saintly partner was the bomber. Good for her!
