i have an idea. What if when the cutscene with swirly d is playing, teleport to him and see what happens
I know I'm a bit late, but there was a glitch (I think in 0.1.3 or .4) where you'd be able to use debugspells in the toilet realm, and if you pressed 7 (ingot) it would spawn Signy's sweet ride. If you got in the car at any point during the Swirly D. cutscene, you would be able to move and even interact with Swirly D, although he wouldn't react to being hit or pushed around. I think there's still a bit about this glitch on the juice galaxy wiki on the toilet realm page.
