Swallow Scene(s)
Trapping the elephant around with its water, the whale began to tease the elephant around like a basketball before devouring it whole. Unexpectedly, a yellow ooze-like substance (supposedly being land) began to spew out of the whale’s blowhole, leaving the whale confused and worried. After a while, the elephant reforms to get revenge against the whale.

Using its truck to suck up the whale’s water, the whale began to thrash around, trying to avoid getting sucked into the elephant's trunk. But the whale had nowhere to go and got sucked right into the elephant’s stomach. Now having a huge belly full of water along with a whale, the whale began to struggle around, which  annoyed the elephant to the point of him receiving a slap with its trunk. The whale then bit the elephant’s tail, and managed to struggle it ways out of the elephant right through its trunk, releasing the whale along with its water.
