Exploding Pineapples

"Like all healthy food, pineapples explode violently shortly after being placed, so don't put any down until you want to blow up some bloons."

- BTD3 Description

A Pineapple is a placeable road item in the Bloons Tower Defense games. It doesn't explode until 3 seconds after being placed. A good defense for M.O.A.B.'s on BTD3 . On Easy Difficulty the Pineapple costs 20 coins and on Medium and Hard it costs 25. The Pineapple debuted in Bloons Tower Defense 3. It pops 3 layers of Bloons except in Bloons Tower Defense 4 and 5, where it only pops 1 layer.

Pineapples are a better option for removing the last few bloons that squeeze through than Road Spikes because the price is 5 money cheaper. However, it should be timed correctly and shouldn't be used against Black and Zebra bloons, being immune to bombs (but road spikes guarantee popping 10 layers of bloon (or 11 in BTD5 ) if that many bloons get there. In BTD5, there is a premium upgrade called Grilled Pineapples which allows the pineapples to take only one second to explode.

 * In BTD4 and BTD4 Expansion, the first upgrade for the Monkey Ace makes it drop pineapples at where the plane is at certain intervals.
 * Sometimes the pineapple in BTD3 will pop 2-4 layers of the bloon.
 * In real life, pineapples are edible and taste sweet.
