Bloon Trap is an upgrade for the Engineer Monkey (or Monkey Engineer prior to BTD6), first released in BTD5 Generation. It grants the Engineer a bloon trap that literally traps bloons that touch it. In BTD5 Generation games, traps are placed sporadically, while in BTD6 and BTDB2 traps are focused on a specific location. Additionally, the Bloon Trap upgrade follows from a different lineage of upgrades; BTD5 Generation games follow it along the sentry-related upgrades, while BTD6 and BTDB2 follow it along the "contraptions" upgrade path, which contains Oversize Nails (9-Inch Nails in BTD5). In BATTD, Bloon Trap returns as a trinket that deploys Bloon Traps that match similarly to its BTD5 Generation counterparts, except with less RBE and can absorb Camos.
The following pages correspond to the Bloon Trap upgrade:
- Bloon Trap (BTD5), the fourth upgrade of Path 1 for the Monkey Engineer in BTD5, absorbing up to 250 RBE.
- Bloon Trap (BTD6), the fourth upgrade of Path 3 for the Engineer Monkey in BTD6, absorbing up to 500 RBE.
- Bloon Trap (BATTD), an item that allows the character to absorb up to a small amount of RBE of bloons including Camos.
- Bloon Trap (BTDB2), the fourth upgrade of Path 3 for the Engineer Monkey in BTDB2, nearly identical to its BTD6 counterpart.
