Billy finds a tiny spider in his room and, instead of squashing it, decides to raise it as his son, naming it "Jeff." Mandy, predictably, wants nothing to do with it. Grim warns Billy that spiders grow fast in the underworld’s influence. Jeff quickly grows giant and starts treating Billy like a father — but with spider instincts: wrapping people in silk, drooling venom, and getting overly attached.
