Ooze ammunition is a capsule containing a sticky substance. If you hit a creature with activated ooze ammunition, it deals acid damage instead of its normal damage type, and the creature then takes the listed penalty to Speed and persistent acid damage until it ends the effects. On a critical hit, the creature is immobilized for 1 round in addition to the other effects. The target can end the effects by Escaping the sticky foam. Other creatures can provide the actions, although doing so deals half the ammunition's persistent acid damage to the assisting creature. A creature that ends the effect still takes the persistent damage that turn.
