1. An unused tower in Bloons TD 1/2 that was
forgotten and was
accessible in the game's files, but in-game it shoots out a high-piercing spike ball which pops a lot of Bloons in a straight line.
2. A tower in Bloons TD 5
Expansion that functions like in BTD1 but with some powerful upgrade and so much more! Also a tower in the XtraCards mod which functions the same as in BTD5E.
