You've heard of Infinity Train, now get ready for Infinity Pencil!
This episode provides examples of:
- Annoyingly Repetitive Child: Three (who's three years old since a Numberjack's number equals their age) claims that she can sing forever. Four is less than enthused and sticks his head in a box to drown out the sound.
- Annoying Younger Sibling: Four gets driven up a wall at the beginning of the episode with Three's singing.
- Catchphrase: Six is heard saying, "Did the trick."
- Department of Redundancy Department: Three often repeats herself in this episode, saying things like, "Taller! Taller!" and "I can't find a four! I can't find a four!".
- Gag Nose: Five imagines a girl's nose growing longer and longer and then the boy sneezing and being pushed back.
- Incredible Shrinking Man: The Numberjacks shrink the Problem Blob.
- Literal Ass-Kicking: When the mop gets longer and longer, it hits a woman on the behind.
- Slapstick: The growing mop knocks one woman in the butt and knocks a hot dog in another's face. Then, when the mop shrinks, the woman gets the hot dog in her face again.
- What Happened to the Mouse?: Three raises the question of why a longer-than-usual pencil is a problem and Five and Six point out that they don't know why it's getting longer in the first place and have to know why so that they can "set things right". They never ask the question of what makes things qualify as "wrong" in the first place, although it soon becomes apparent that the pencil's too long to write efficiently with.
