The Pineapple Water Tower is a water tower seen in Lilo & Stitch: The Series.
In "Sprout", it also becomes Experiment 509's (Sprout's) one true place. When Sprout lashed out at Mertle, causing her to accidentally break his flower pot open, he rooted himself into the ground and created a forest of destruction, while growing exponentially large. Eventually, Stitch managed to lasso the original Sprout and uproot him. Sprout was then contained in the pineapple-shaped water tower that had been slated for demolition, causing the Sprout replicas to die off without the original.
