the giant gerbils, as well as the huge grasshoppers, needs pumbaa to give them extra food because of their size.

The subject of the sentence is "the giant gerbils" (plural). Phrases like "as well as the huge grasshoppers" do not change the subject's number. So the verb must agree with the plural subject, requiring "need" instead of "needs".
