What three things made Bugs run away?
Much like in Hair-Raising Hare, Bugs (after being flooded out of his rabbit hole while sleeping during a heavy rain) finds himself trapped in the castle of an "evil scientist" (the neon sign outside his castle says so, punctuated with a second flashing line, "BOO"), a caricature of Boris Karloff, and needs a living brain to complete an experiment. When Bugs awakens, he is terrified when he sees the scientist ("Eh, eh, eh, w-w-what's up, doc?"), a sarcophagus ("What's going on around here?") and the robot experiment ("Where am I anyway?"), eventually running away after the terror of seeing all three. The scientist sends out an orange, hairy monster he calls "Rudolph" to retrieve him, with the promise of being rewarded with a spider goulash.
