Scuba Monkey

"The Scuba Monkey is essential on any water covered track as a replacement for Dart Monkeys, and its powerful upgrades make it a must for the later rounds."

Scuba Monkey
Scuba Monkeys are basically just Dart Monkeys that are placed on water. They throw darts at nearby bloons that are in its range, and pop one layer on one bloon (without upgrades, of course!). They have the same range and throwing speed as Dart Monkeys. The Scuba Monkey looks like a wet Dart Monkey with a scuba mask, flippers, and a snorkel. He costs $520 on Easy, $570 on Medium, and $610 on Hard. Upgrades are as followed:

Path 1:
Long Range Darts: Scuba Monkey can throw a little bit further than normal. $210 on Easy, $255 on Medium, and $310 on Hard. His gear is now green.

Super Range Darts: Scuba Monkey throws even further than before. $270 on Easy, $315 on Medium, and $365 on Hard. His gear is now red.

Mermonkey: The Scuba Monkey transformed into a Mermonkey that throws tridents instead of darts. The tridents pop 3 layers per bloon.

Ocean Lord: The Ocean Lord is capable of throwing two tridents at bloons, while shooting powerful jets of water at bloons that confuse them so that they move backwards for a short period of time. The jets of water affect 3 bloons at once.
