A touch of Monkey napalm pops additional Bloons every 2 seconds after impact for 6 seconds
~ Official Bloons TD 5 description

Burny Stuff is the second upgrade for Path 2 for the Mortar Tower in BTD5, or the second upgrade of Path 3 in BTD6. This upgrade adds napalm that sets Bloons on fire for 6 seconds. Every 2 seconds, one layer gets popped. If a Bloon gets hit while the Burny Stuff upgrade is activated, the Bloon will have monkey napalm and be on fire for 6 seconds.

In BTD5, it costs $430 on Easy, $500 on Medium, $540 on Hard and $600 on Impoppable. In BTDB Mobile, it costs $750.

Tower Appearance[]

The tower upgraded to the Burny Stuff upgrade looks like the original Mortar Tower, except with a fiery design on it.



Its burning damage-over-time is effective at chipping down the health of bloons, and allows Mortar to damage Blacks until getting The Big One.


  • It is very strong in Bloons TD Battles due to its effectiveness against lots of early grouped bloons.



  • The Burny Stuff tower's appearance is the same as the second upgrade on the first path for the Mortar Tower.
  • The Burny Stuff upgrade is good for thinning out layers of bloons, especially Ceramic Bloons.
  • This upgrade works similarly like the Corrosive Glue upgrade from the Glue Gunner.
  • The Spiked Mines explosions add the same burning effect to Bloons.
  • With this upgrade, the Mortar Tower can pop Black and Zebra Bloons, they will be not popped by the explosion, but they will be popped by the napalm.
  • Bloons can be affected by ice and napalm at the same time.
  • This upgrade makes the Mortar Tower act similarly to a Molotov because when somebody throws it, it explodes and gets napalm on somewhere.
  • The explosion turns orange after a player upgraded the Mortar Tower to Burny Stuff shown below.
