Crocodile

A crocodile is a reptile that mostly lives near the water in rivers. In the Smurfs comic book story "Gargamel's And The Crocodile" as well as its HERO: The Guardian Smurf story adaptation, Gargamel comes across a baby crocodile that he buys from a merchant and keeps as a pet to raise in the hopes of using its skin for a Smurf-catching formula. However, the crocodile in its mature state ends up crawling its way into the river where it threatens all people who go near it, including the Smurfs. Believing it to be a dragon, some knights went after the crocodile to capture it and put it in the king's moat against Gargamel's wishes.
