Octopus

The Octopus is a special agent that costs 100 MM, can only be placed in water, and shoots ink at bloons. The ink is so sticky, that it makes projectiles stick to bloons! Projectiles that stick to bloons pop them overtime, like Corrosive Glue or Napalm. Only 1 projectile can stick to bloons, and only 5 projectiles can stick to 1 bloon at a time. Ink stays as long as 0/1 Glue, and when it comes off, all the projectiles fall off. Here is the list of projectiles that can stick:

Darts: 1 layer per second

Tacks: 1 layer per second

Acorns (Angry Squirrel): 1 layer per second

Watermelon Seeds (Watermelon Spitter): 1 layer per second

Grapes: 1 layer per second
