Spike-O-Pult (BTD5)

"Converts the Dart Monkey into a Spike-O-Pult, a powerful tower that hurls a large spiked ball instead of darts. Good range, but slower attack speed. Each ball can pop 18 bloons."

- Bloons TD 5 Description

"Catapult fires spiked balls that can pop 40 bloons."

- BTDB Mobile description

The Spike-O-Pult is an upgrade for the Dart Monkey that appears in BTD4, BTD5, BTD Battles, and Bloons Monkey City. It changes the projectile of the Dart Monkey to a large spiked ball with higher pierce but slower attack rate.

In Bloons TD 5, it is about 3x bigger than previous versions. The Spike-O-Pult is the third upgrade on the first path of the Dart Monkey; and it costs $425 on Easy, $500 on Medium, $540 on Hard and $600 on Impoppable.

Trivia

 * The Spike-o-pult appears to be based on the onager, a type of catapult that uses tension to power the shot. The mangolnel is named after a wild species of donkey because of the intense force with which the projectile is shot, causing the device to jump forward every shot.
 * The way the monkey holds the Spike-O-Pult changes as the Bloons TD series progresses. In Bloons TD 3, he holds it with his right hand, in Bloons TD 4 he holds it with his tail, and in Bloons TD 5, he holds it with both hands.
 * The Spike-O-Pult is an upgrade to the Dart Monkey, but in BTD3 and before the Spike-O-Pult was its own tower. This makes it the first tower to become an upgrade for another tower.
 * In BTD5 if you have Splodey Darts, it won't explode until they have popped 18 bloons or hit a lead bloon, so Splodey Darts are not very useful with Spike-O-Pult.
 * If players place a 2-0 Dart Monkey near a Dart Monkey with Super Monkey Fan Club upgrade, then if the player uses the ability and once the 2-0 Dart Monkey has transformed into a Super Monkey, upgrade it to Spike-O-Pult then it change into a Spike-O-Pult Dart Monkey but it will shoot as fast as a Super Monkey for the duration of the Super Monkey Fan Club ability. It also happens with the Juggernaut upgrade if players upgrade to it fast enough.
 * This only occurs in flash versions of BTD5, BTD Battles and BMC (?).
 * If it has already been upgraded, it will turn into a Super Monkey who occasionally throws spiked balls.
 * Although the Dart Monkey appears to have shrunk in size with the Spike-O-Pult upgrade, it is actually the same size compared to a normal Dart Monkey.
