"I'm not scared of some stupid box with some stupid thing you probably stuffed in to scare me or make fun... of... me..." Candace stared and Phineas and Ferb grinned widely.
"...Why?.." The teen blinked in confusion.
"No reason." Phineas shrugged, looking as his sister gingerly took out a little chain with a Ducky Momo charm.
