Now that Roxy had turned red there was no way that Kat wasn't going to let this happen. "Tomaaaaato," she teased in a sing-song voice, splashing a bit of water at her sister. Turning towards Charlene she spoke in a stage whisper, cupping her hand over her mouth so that it looked like she was trying to keep Roxy from hearing. "Those are this vegetable - or fruit - thing that we eat. They're really, really red and Roxy toooootally like, looks just like one when she gets all embarrassed. Like right now!" Giggling, Kat pointed at Roxy and then did as Charlene wanted and cupped her hands over her ears. If the mermaid could make people do things they she definitely didn't want to hear. Maybe a little bit... maybe after Roxy did something.
Floating there, Kat watched, wide-eyed and curious, to see what her sister would do. Although she was feeling the oddest desire to go and turn into a penguin. Because wouldn't that be the most awesome thing ever? Show off her form to Charlene?
