This creature is the closest the 3d realm has to sabretooth tigers. Its right eye acts as a radar, and can move the eye to see in all directions (even through the sides of its head) for prey. It has no ears, but its radar eye would make ears obsolete. When it hears footsteps close to its domain in the 3d world, it rapidly moves the eye until it locks on to the intruder. When its target is found, it stealthily moves to their location, lurking behind them, until it suddenly leaps out and lunges at them with its mouth agape. You can tell where its domain is if there is a lot of exposed organs and guts scattered about on the floor of a cave.

Reports of another trix creature in opposite proportions to them has been sighted hunting and living alongside Blargutrix, however none can make out its features until Blargutrix appears, and their demise follows shortly after.
