After overhearing Mayor Meanswell tell the kids the story of Johnny Sportscandyseed, Robbie decides to build a time machine to go back in time and prevent him from ever planting any sportscandy trees in LazyTown. When he succeeds and all the sportscandy disappears as a result, it's up to everyone else to get Johnny back to his original time!
Tropes:
- Ambiguously Human: Johnny Sportscandyseed can plant trees at will with a magic staff.
- Continuity Nod: Johnny B. Badd appears briefly when Robbie travels back to the 50s.
- Shout-Out: Robbie's time machine bears a slight resemblance to the TARDIS from Doctor Who.
