Heckin' Happy! (Patreon)

YEAH! SMASH! WHAM! HECKIN' BOOM, even! The more excited Nell gets, the faster her growth rate speeds up, and the harder it'll be for her to stop it. But Nell's not one to worry about consequences later when there's fun to be had right now, and what could be more fun than jumpin' around making a whole bunch of smashy mess? HECKIN' NOTHING, YEAH!
