Is this the end of Button House? The ghosts watch something going up in blazes.
A flashback sees Mike and Alice bickering. He has purchased a real life bear for the guest house. Alice things it is tacky.
Caveman Robin is upset. The bear in the house brings him nightmarish reminders of being chased by bears in prehistoric times. Fears Robin thinks he needs to conquer.
It is a case of what caused the fire and there are a lot of incidents that might have started it.
What was certainly on fire were the ghosts making jokes about vegan food. The slop produced masquerading as a vegan alternatives was really a case of nightmares. Yuk.
