Lizards

Lizards are Mobs that spawn in the biome, The Swamp. They are Neutral, but sometimes if you hit one, they will fight you. These mobs also fight hostile mobs as well, but they aren't too strong against them. Lizards drop Scales which are used with any Carpet to make a Scaly Carpet.

Strategies against them
Lizards may drop Scales, but when they're in hordes, or if you find a Block known as a Lizard Home, you can always destroy the block, but you can use it to your advantage and use their Rare Drop to make Scaly Carpets.

They can also spawn a larger version of themselves called the Kimodo Dragon. which stuns you for 6 seconds, and they do 1 heart of damage on Easy, 2 hearts of damage on Normal, and 3.5 on hard. You can hit them from a distance with your Bow since they actually take a lot more damage from a Bow.

Lizards also take Splash damage from Arrows as well. This adds an advantage if you have a Bow.
