OP needs to coat the inside of toilet bowl with a spray substance that would make the bowl more slippery and less likely to stick to

1st off it’s a cockroach. If anything was going to survive it would be this. 2nd ewwww and finally 4th a potentially disastrous invasive species being rediscovered is not uplifting.

Side note: ewwww was worth 2 points
