Underground unit under Colonel Tipid, expected to be busy the moment Operation Ruin begins.
When Justice Light cleared his sapper crew out of the trap tunnels, he sent them to the Frothing Tunnel Moles. He told Sneaky Tyler C to find Colonel Tipid, report that the Sluggalos are trained sappers, and try to join up — 'They're sure to be busy in the coming hours.'
The recommendation is a real endorsement: the slugs spent days setting manual tripwires with their mouths and threading the eastern approach, work that translates directly to whatever tunneling and demolition the Moles will need once Operation Ruin launches at the end of the timer.
The tunnel-warfare unit the sluggalo sappers are directed to join for the coming offensive.
