Tangler is a gun that fires shotgun blasts of rectangular bullets that bounce off walls. Enemies hit will gain a rectangular appearance.
Iron Stance - If the player also has Heavy Boots, the gun's damage and knockback are increased by 20%, its shot speed is increased by 50%, and its reload time is decreased by 20%.- Primitive Shapes - If the player also has Quad Laser, Tangler's shots become much larger and deal 50% more damage, but travel very slowly. Quad Laser's shots become rectangles and travel faster.
- Spengbab - If the player also has Sponge, knockback and range are increased by 50%.
- Full Circle - If the player also has Rolling Eye, Tangler appears round instead of rectangular. Deals increased damage and turns enemies round instead of rectangular, but reloads slower (2.0 seconds) and often causes the game to crash.
- Jammed enemies, the Bookllet variant in the R&G Dept., and the ghost of Blockner are unaffected by Tangler's visual distortion effect.
- Tangler's visual distortion effect applies to bosses.
- The synergy with the Sponge is a reference to Spongebob Squarepants.
