Jeffy's Web (S04E13)

While exploring beneath his house, Billy stumbles upon his unusual “son,” Jeff the Spider, who has just laid a new batch of eggs. Jeff seeks to mend their relationship, hoping Billy will care for the hatchlings since he faces imminent death once they emerge. Overwhelmed by fear at the sight of Jeff, Billy bolts, leading to a chaotic car chase. As the eggs begin to hatch, Grim intervenes, choosing to refill Jeff's hourglass, thereby extending his life so he can keep frightening Billy a little longer.
