Debuted in Bloons Tower Defense 3, the Pineapples are a placeable road item in the Bloons Tower Defense games. Even though it doesn't explode until 3 seconds after being placed (aside for the Grilled Pineapples Premium Upgrade in BTD5 and BTD5M), it is still regarded as a good defense for M.O.A.B.'s on BTD3. On Easy Difficulty the Pineapple costs 20 money, and on Medium and Hard it costs 25 money. It pops 2-4 layers of bloons except in Bloons Tower Defense 4 and 5, where it only pops 1 layer.
