The shifting slime makes one pseudopod attack against a target it is grappling that is at least one size smaller than itself. If the attack hits, the target is swallowed, and the grapple ends. The swallowed target is restrained, it has total cover against attacks and other effects outside the shifting slime, and it must make a DC 13 Constitution saving throw at the start of each of its turns taking 3 (1d6) acid damage on a failure. If the shifting slime used its adaptive ability to become immune to a damage type, the damage dealt to the target on a failed save becomes that type instead. The shifting slime can have only one target swallowed at a time. If the shifting slime dies, a swallowed creature is no longer restrained by it, and may move freely as the body of the slime quivers and neutralizes into an inert puddle of goo.
