The Sand Shark (also known as "The Beast" and "The Shark") is the giant minor antagonist shark in the Aladdin TV series.
Raiders of the Lost Shark
The Sand Shark, or the Beast as Merc calls him, is first seen going around Agrabah on a rampage. Merc has Aladdin and his friends help him capture The Shark and he uses Abu and later Jasmine as bait for the beast to eat him.
When the shark gets out of the sand and flies over Merc's ship, everyone sees that his chest is covered with treasure.
Later, when Aladdin and the others find Jasmine, the shark approaches them. They get on a rock and the Beast tries to get them off so he could eat them. The gang is then rescued by Merc. When Aladdin and the others make the shark approach them as Merc tries to kill him, the beast runs into a rock and becomes unconscious.
When the gang goes back to the palace, they tie the shark in front of him. The next morning, Merc frees the shark and he swims away.
Beast or Famine
Merc is going after the shark and about to throw his harpoon at him. But the shark then gets caught by a tribe of rat-like people's harpoons and he gets eaten by them. Only the shark's bones are seen for the rest of the episode. Aladdin, Abu, and Merc use the shark's bones as a new ship since Merc's old one got wrecked to go rescue Genie from the rat people's hostile leader, the Shaman.
