how to go wumbo on pesticide not required is to wait for the time to be 15:00 on the timer/clock. try not to die on 0:00 to 14:00 so you could get wumbo and win a run. to win more easy is to get any weapon from the store for max, wait another day and buy the same weapon for max, then upgrade the object, buy more weapons from the store and buy max of them every day, then max out the upgrades on the weapons and survive for 0:00 to 15:00

also you can get a achievement by winning a run as joe/other frogs and killing a boss while wumbo.
