A Silly Particle is a particle of pure silliness that may float anywhere in Toontown. Silly Particles were a discovery by Doctor Fissionton that is said to cause absolute wackiness, and could be key to driving the Cogs out of Toontown.
On March 29, 2018, a grand search began and Silly Particles became present across all of Toontown in which they can be found in the most wacky locations of the playgrounds, streets, Toon Buildings, and even Cog Buildings. Toons were expected to work together and collect 2,600,000 Silly Particles to help Doctor Surlee with his research. A Toon could collect up to 31 Silly Particles before being unable to collect any more. For every five Silly Particles collected, a message from Loony Labs would appear after collecting five. Once a Toon collected 31 Silly Particles, they were instructed to visit Doctor Surlee in Silly Street to trade for five jellybeans per Silly Particle.
After previously been able to collect only 31 Silly Particles, the silliness of April Toons Week increased the limit to 50 and had become worth double in value.
On April 3, 2018, 2,600,600 Silly Particles were successfully collected. Professor Prepostera can now be found in Silly Street to offer a brand new ToonTask for Toons to help find his access card and gain access to Doctor Fissionton's location. Toons can, however, still continue to collect Silly Particles if they wish.
- The discovery of four types of particles were documented in Doctor Fissionton's " " text file. Besides Silly Particles, the other known particles are Antisillions, Glitchinitives, and Phooeytons.
- Unlike treasures, Silly Particles could spawn in very obscure locations that may force Toons to venture outside of a single zone.
- Some Silly Particles can spawn in the Grey.
