Tigra in Murderworld by Jamal Igle

2015 HeroesCon commission. He hit/incorporated all the points referenced.

Tigra,Arcade, and the White Rabbit. Tigra is in Arcade's Murder Wold. After beating the laser pointer gauntlet and the suffocating quicksand litter box, she is entangled with the "murderous ball of yarn". It is a large, sentient ball(5-6' in diameter) that believes it is a industrial engineer, Malek England{ think the Swamp Thing's origin, but in the textile/craft industry).

Arcade and the White Rabbit faces are visible in a large video screen(s) on the wall( the back wall is effectively a video screen). They are watching the battle and offering Tigra words of "encouragement"
