A worm-controlled roller-skating circus bear, revealed as a level-19 boss — freed and mercy-killed by Carl.
Heather is a level-19 Neighborhood Boss: Grimaldi's beloved old roller-skating bear, weeks from retirement when the cataclysm hit, transformed into a worm-controlled hunter that runs down prey for the clowns to feed on. Forced by Tsarina Signet's hostage-hold on Princess Donut, Carl fought her solo: her mind-invading worm-claws burrowed into his bare legs and spoke in his head before he broke free with Protective Shell, then doused her in moonshine and set her ablaze. When his Lucky-Bastard scratcher landed on 'Custard' instead of Fireball, the healing custard paradoxically killed the parasitic worms and mold — freeing the real Heather, an exhausted elderly bear who silently begged for death.
Carl crushed her skull to end her, winning his first solo boss battle and hitting level 15. Her blood flew to Signet to power the summoning.
An eight-foot black bear on roller skates (fused pink clown hat, skinless skull face, red eyes, mop-like white worm-claws, pink tutu) in her cursed form; freed, a tired old silver-muzzled black bear on all fours with newly formed eyes.
A named circus neighborhood boss and a tragic mercy-kill for Carl.
