Now living on their own and away from parental control Norb and Dag realise they can stay up all night if they want. What starts out as a wild good time quickly turns into a journey into the madness of sleep depravation...

The ancient legend from the grey mists of earliest time tells of a scaly terror called 'Old Gramps', a fish so large he can swallow a Swede. When Dag runs smack into Old Gramps, the time has come to find out the truth.

Daggett's tired of being 'a creature whose only natural defence is to hide in his dam'. Despite his natural ineptness, and Norb's best efforts to dissuade him, Dag pursues the Martial Arts.

The boys learn the hard way that being on TV isn't all it's cracked up to be when they let a famous nature filmmaker film them and he broadcasts a "funniest videos" style film instead of the serious documentary they expected.

Daggett and Norbert learn how to mark territory with their scent glands. Their fraternal jealousy kicks off a marathon of territory claiming across the dam, the forest, and the entire country. The boys finally learn their lesson at the hands of some rather smelly lumberjacks.
