Humane Grendel control! This Grendel Trap COB by Slink injects a vehicle which acts as a grendel trap. It will only be sprung when pushed by a grendel. It can be moved around by first pressing on the truck to turn on the engine, and then pressing any of the four sides. There is a safeguard to prevent the trap from disappearing completely off the top or bottom of the screen. Turn the engine off to stop the trap from moving further. When a grendel has been trapped, the key will flash. You may release the grendel by pressing on this flashing key.
The C1 class numbers used by Grendel Trap are:
- 3 1 211
You can download it from TreeSprite's Grove, in the Slink's Treasures section.
