The Cartoonival Tower is a large tower of silliness found in the center of the Cartoonival Grounds. By throwing portable pies at dummy Cogs, 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 tower became the central location of where Toons can purchase brand new clothing, accessories, and other exclusive items.
In the 2.7.0 update released on December 15, 2020, assets for the event were updated to reflect the Cartoonival rebrand, with the new Cartoonival logo now appearing on the tower.
- During 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 three texture artists. The bottom to the rectangular yellow part with the blue stars was made by Slate. The round part with bands around it was made by former staff member Boo Boo, and the blue 3D star to the top was made by June.
- Garfieldo designed the full model for the tower.
- When the event area reopened as "Barbecue Headquarters" during April Toons Week in 2015, the tower was affected by gravitational anomalies.
- Toons can collide with the Cartoonival Tower by using cannons as a method of bouncing from one cloud to another.
- During ToonFest 2019, the tower lost the letter "F" from its iconic logo. This resulted in a decision made by Riggy Marole to give ToonFest a new name, depending on what Toons voted. On September 20, 2020, it was announced during the "Behind the Tooniverse" panel of ToonFest at Home that the new name for the event would be Toontown's Cartoonival.
