Loony Labs ToonTasks are special ToonTasks that are offered by Professor Prepostera at the Toontown Central Pet Shop during Toontown's wackiest holiday, April Toons Week. The prank was first made by Sir Max on April 1, 2016, who made it seem like doodles have finally returned to Toontown, only to end up having both Professor Prepostera and Doctor Dimm using the Pet Shops as the temporary base of Loony Labs. This is also the first time the Silly Meter prototype made an in-game appearance.
Currently, there are only two available ToonTasks. It is unknown if more ToonTasks will be implemented in the future.
