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."

- BTD4 Description

A Pineapple is a placeable road item in Bloons Tower Defense games. It explodes in 3 seconds after being placed. A good defense for M.O.A.B.'s and B.F.B.'s. On Easy Difficulty the Pineapple costs 20 coins, on Medium and Hard it costs 25. The Pineapple debuted in Bloons Tower Defense 3. It pops 3 layers of Bloons, except for in Bloons Tower Defense 4, where it only pops 1 layer. Pineapples are a better option for removing the last few bloons that squeeze through than Road Spikes due to the price being 5 money cheaper. However, it should be timed correctly and shouldn't be used against Black and Zebra bloons, due to they being immune to bombs (But the Road Spikes are instant, while the Pineapple takes some time). In BTD 5, the Premium upgrade Grilled Pineapples, when used, only takes 1 second to pop.

Trivia

 * In BTD3, BTD4, Bloons Tower Defense 4 Expansion, and BTD5, there is a 3-second countdown timer displayed on the pineapple.
 * Along with Road Spikes, Pineapples can be a lifesaver if the bloons start making it through your towers.
 * Pineapples are good for exposing and thinning out camo bloons or lead bloons.
 * In BTD4, BTD4 Expansion and BTD5 the first upgrade for the Monkey Ace enables it to drop pineapples on its path at certain intervals.
