fishingtom - Hmm. Being a red/black snake, maybe he/she just felt a sudden kinship to the red/black bike.

Given your location, I agree with you that it's likely not a coral, but rather a scarlet king snake, which mimics a coral. Since you're 5 years in, have you done the air filter? Might be a good time to finally do that task if you have not, and evict the little critter while you do.
