Six (6) is a yellow Numberjack. He has blue eyes and is the eldest of the main Numberjacks. He enjoys doing tricks and going on adventures. He’s also in charge of deciding who gets to go out and if he sees a meanie, he feels disgusted. 6 does help 4 and 2 improve their jumping but 8 is better as he knows more tricks and he helps 6 with more tricks
- Six is the first even Numberjack on a mission to encounter Spooky Spoon, as seen in Stop and Go.
- In many episodes he is yellow but in some, he is orange.
