Question

add or remove commas, if necessary, until the sentence has correct punctuation. my rabbit hides carrots, under sheldon planktons couch.

Explanation:

The phrase "under Sheldon Plankton's couch" is a prepositional phrase that functions as an adverbial phrase modifying the verb "hides". There is no need for a comma between the direct object "carrots" and the prepositional phrase that tells where the hiding occurs. So we remove the comma.

Answer:

My rabbit hides carrots under Sheldon Plankton's couch.
