Popo

The Popo is an enemy who made its debut in A Link to the Past, and returned in Four Swords Adventures. It resides in dungeons such as Eastern Palace, Desert Palace, Misery Mire and Temple of Darkness. It is a sentient mass of tentacles that moves along the ground and will harm Link if he touches them. Its movement is shambling and without specific direction; it won't actively seek out Link and will often move in a different direction entirely. Rather than a threat, it mainly acts as a nuisance and is only likely to cause harm if other enemies are involved. They do however appear in large swarms on occasion, but their slow movement means that even as a large mass they are not particularly dangerous. They can easily be defeated with a single hit of most weapons, and often leave behind Rupees.

Trivia

 * Popo were erroneously called Leevers in the Top Secrets booklet that was originally packaged with A Link to the Past.
