The Grab monster ability stays that once the monster have grabbed something with a body part, he cannot use that body part, and that the limit for grabbing is the number of body parts the monster have. I have read other post about how grab works and the limits of things like a Kraken, but oozes pseudopods (to me) seems like "appearing" from the main mass of the monster at will, so, How many "pseudopods" have an ooze?, and thus, how many things can an ooze grab at the same time.

Reference of grab:
Grab: 1 action
Requirements The monster's last action was a success with a Strike that lists Grab in its damage entry, or it has a creature grabbed using this action. Effect The monster automatically Grabs the target until the end of the monster's next turn. The creature is grabbed by whichever body part the monster attacked with, and that body part can't be used to Strike creatures until the grab is ended.

Using Grab extends the duration of the monster's Grab until the end of its next turn for all creatures grabbed by it. A grabbed creature can use the Escape action to get out of the grab, and the Grab ends for a grabbed creatures if the monster moves away from it.
