In 0 and 1's bedroom, 7 is telling them a bedtime story of the Numberjacks at night; then an agent in their pajamas reports that a man is washing his car in the middle of the night.
In the Cosy Room, 3 and 4 argue over entertaining 5's buddy blocks; they try to share them, but the blocks get bored and wander off; a call comes that two boys are arguing over a ball, so 3 flies out.
In the gym, 6 can't jump on the seesaw and 4 feels ill too, because they've both got the dreaded lurgi; a boy can't stop bouncing up and down on a trampoline.
A girl's bedcover is too small and then too big; 6 and his buddy tiles are making patterns on the floor and flying around; a teacher covering a table for painting finds the sheet gets too small, then too big.
Needing help to sort her beautiful things, 3 calls on 0 and 1; a girl's toys are being jumped into groups of animals and trucks; in the park, picnickers are in groups by age, or by the color of their tops.
Numberjack 1 plays a trick on Numberjack 4, always making the number of buddy blocks on the seesaw unbalanced; a boy has one sock and three shoes, but only two feet.
The Agents call in when a boy's toys have extra things appearing mysteriously.
Even numbers are disappearing.
