Norbert is a full four minutes older than Daggett and he is also the tallest of the two beaver brothers. However, when Daggett has a sudden growth spurt, Norbert must cope with the fact that he's no longer the biggest beaver in the dam.
Norbert tries everything to get himself taller than Dag but doesn't succeed exactly. That night, things are no better as Norb has a nightmare about Dag being taller than him.
When it's "Measuring Day" comes again, Norb tells Dag he doesn't want anymore of that day. Defiant, Dag starts the measuring but not before bending down so he's short and Norb is tall again.
