Once he swallowed all of the baby fish, he approached a family of crabs, who lived in the same pool, and told them the same story about the drought and the pool.
A drought is coming!
Crabs are different from fish, they are much more wise and have more experience to base their decisions off of. The oldest and biggest crab acted intrigued and asked the pelican to bend down and tell him more.
Tell me more!
I must carry you away!
In reality, the crab had concluded that the waterfall was still flowing rapidly and a drought could not be coming. He also decided the pelican was not a creature they needed in the pool. As the pelican bent down to tell the crab his lies, the crab grabbed the pelican's neck and squeezed it until the pelican was dead.
Once he died, the pelican's beak opened and all the baby fish and their mother swam back into the old pool. In the end, only the pelican suffered. Eventually, even Ruan swam back up the river to the old pool where he was reunited with his family and went back to doing as his father taught him , laying at the bottom of the river pretending to be stone.
