You come upon a Kosher Kube. Unlike the green ones, who are monsters you can fight, this red one is just sitting there... blocking a doorway.

This is a Skill check, available in the Dungeon. Success gives you access to the doorway, which you can then click on to enter Herschell's Kosher Kube Kitchen. Failure leaves you stuck inside the Kosher Kube, costing you 5-29 HP.

To successfully charge through, (Arm+d4) needs to be higher than a random number from 5 to 19.
