| ~ Description |
The Spike-o-pult is a tower introduced in Bloons TD 3 that launches a spiked ball with 1 damage and 6 pierce every 1.65 seconds. It is best used against large, clustered groups of low-ranking bloons. Upgrades increase its range, attack rate, pierce, and projectile size.
In later BTD games, the Spike-o-pult appears as an upgrade for the Dart Monkey.

Trivia[]
- The Longer Range upgrade does not change the tower's appearance.
- The Multi Shot and Juggernaut upgrades also reappear in later BTD games as upgrades for the Dart Monkey (with Multi Shot becoming Triple Shot in BTD4 and Triple Darts in BTD5 and later).
