FIRE (BcTD)

Overview
FIREs (Flamin Indestructible Rushing Entity) are special blimps with special immunities to explosions (like a Black Bloon or Zebra Bloon) and heat/flame attacks (like a Purple Bloon). When popped, releases 4 DDTs. It has 1,200 HP. They are faster than MOABs but slower than DDTs, Purples, Pinks, Yellows, and Greens.

Quote
"FIREs are the parents of 4 DDTs. With extra immunities and triple the health, these blimps are no laughing matter."

Strategies
Any tower that works on a Tiger Bloon can work on FIREs, so spreading those towers across the track should be able to deal with them. Fortified and/or lead coated FIREs can be dangerous, as their high hp/immunity to sharp attacks can let them charge straight through your defense. MIBs, as always, are one of the best ways to deal with them fast.
