 "Slap Happy" (teleplay by Barry Stringfellow, written by Keith Kaczorek): Beaver fact: Beavers use tail slaps on water to warn others when danger threatens. Dag abuses this natural alarm, causing Norb to call in their dad to set things right. --- "Home Loners" - Daggett and Norbert are both unaware that the other is at home and go through a series of near-misses and close calls until they both think someone else is in the house.
