The ToonFest Tower is a large tower of silliness centered around the ToonFest Grounds. By throwing pies at a Cog dummy, Toons can speed up, slow down, and reverse the direction of the platforms around the tower. Inside the tower is where Token Takers sell all sorts of exclusive prizes.
At the bottom are four rotating disks composed of a merry-go-round colored yellow, blue, and red with each getting smaller. Each platform spins the opposite direction of the one larger than it. At the center of the four platforms in a blue and red cupcake, with a pillow stuck out of the top. On top of the pillow is a blue hat-like object with four party streamers connected to it. Out of the hat is a stem which connects to the ToonFest logo and a platform that Toons can stand on if they somehow manage to get there via means of glitching. Atop the viewing platform is a party hat connected by two gloves.
The tower returned for ToonFest 2015 with a different design of a larger blue and red cupcake consisting of four locked doors, and giant ToonFest tokens placed on top replacing the pillow. Following ToonFest 2017, the logo was changed due to Toontown Rewritten's rebrand. The ToonFest Tower became the central location of where Toons can purchase brand new clothing, accessories, and other exclusive ToonFest-related items.
- In ToonFest 2014, the ToonFest Tower had no purpose other than the ToonFest hot air balloon manned by Alec Tinn where Toons could ride to the top of the tower.
- According to Slate in one of her YouTube livestreams, the ToonFest Tower from ToonFest 2014 was made by all three texture artists.
