Looks like our favorite cereal mascot got having a wrong turn of "Follow Your Nose" thing hehehe. X3
He smelled an cursed flower mimicking with the scent of Froot Loops cereal causing Toucan Sam's feet forced to grown huge as per smell of the flower and spawning an colored vines on the ground just like from the cereals and tickling him. The more he sniffed the flower, the more his feet to unlimited growth.
