- The Toon takes out a Birthday Cake and throws it at the targeted Cog.
- If the gag hits, the Cog is hit by the Birthday Cake with a large pink splat.
- If the gag misses, the Cog jumps to the side and dodges the Birthday Cake, making it vanish.
The damage of the Birthday Cake increases by one point for every 76.9 skill points gained.
- In Alpha, the first appearance of Birthday Cakes, despite not being a physical gag used by Toons, came from Slappy's hot air balloon that was located on the plate.
- The second appearance of Birthday Cakes was during Sir Max's birthday. Flippy temporarily replaced all his Whole Cream Pies with Birthday Cakes in his pie stand to celebrate Sir Max's birthday.
- The third appearance was during Doomsday that was used by Flippy to defeat the Director of Ambush Marketing. Toons, however, could not use the Birthday Cake or any other gag besides the Whole Cream Pie during the event since gags were generally unavailable for the duration of Alpha due to lack of Cogs and the battle system.
- A single organic Birthday Cake is able to defeat an unlured level nine Cog.
