Haunted Couch

The Haunted Couch is a very strange item. It randomly appears on a track (15% chance) Between Oct. 1st and 31st. If you place a monkey on it, you will get the "Sat on a Cobweb" achievement. It causes different effect depending on how long it sits there.

Effects
1-5 Rounds: Occasionally throws cobwebs (10% chance) that entangle the bloons, stopping them for 3 seconds.

6-10 Rounds: Fire rate is 10% slower, due to spoooooooooky ghosts. Also, this means that bloons in the towers range slow down by 5%.

11-20 Rounds: All nearby monkeys look desaturated and their HP starts slowly draining. (1 HP every 15 seconds.)

21-25 Rounds: Fires at 500% speed, and pops 2 extra layers.

26-29 Rounds: Stops attacking altogether.

30 Rounds: The tower and couch both dissappear.

Exceptions
Super Monkey-2x longer

Buildings-Cannot be placed on it, not affected by HP drain.

Non-living towers-All effects, except for the 11-20 and 30 round effects, will not apply.
