Capybaras are new mods found in swamps, mangrove swamps and river biomes. They will spawn anywhere on those, usually in groups of 3-4 capybaras, but will spawn way more frequently at Capybara's Paradise, also found in mangrove swamps.
Capybaras will follow you if you hold a melon slice. It also allows you to breed them.
Capybaras are semiaquatic animals, so they spawn more often near water bodies. However, they do not need water in order to survive.
Capybaras are really fast swimmers. If you grab a melon slice in front of them while swimming, they'll catch up to you in a heartbeat.
Added Capybaras' Paradise:
A new structure found in mangrove swamps. Here, capybaras spawn more often than in the rest of the swamp, as well as staying closer to these structures.
You'll find lots of watermelons scattered around, as well as small ponds with thermal springs, currently being the only way to obtain this new block.
Added mandarins:
Added mandarin bushes:
Despite being totally not realistic, mandarin bushes are the way to get the new fruit.
You can find mandarins, mandarin leaves and flowering mandarin leaves in these bushes.
These bushes only spawn on the plains biome, so make sure to gather some saplings to plant them anywhere else you might want to have it.
Added mandarins:
A new food type. Eating this will give you 2 hunger points + the "Sweetened" status effect for 5 seconds.
You can put a mandarin on a capybara's head by right-clicking them while holding a mandarin. To remove it, just right-click the capybara while sneaking, and the mandarin will drop right off.
Added mandarin leaves:
A new decorative block that when broken, has a chance at dropping either mandarins, a mandarin bush sapling, or sticks.
This block has a second variant, the flowering mandarin leaves, only being visually different.
Added thermal springs:
A new decorative block. This block emits steam particles from the water blocks above it in a 5 block radius.
If there's water below it, the thermal spring essentially becomes a geyser, shooting steam particles up.
The only way to find this block is to find a Capybaras' Paradise structure, where the ponds will have this block at the bottom of them.
The particles are a bit performance intensive, so use these sparingly (spacing them 10 block apart should give you the most use out of them).
Added sweetened:
A new effect. While having this effect, all food gives you 50% more hunger points (1.5x). For golden apples and enchanted golden apples, as well as the 50% more hunger points, you'll also get 2 more absorption hearts (4 health points).
This effect is only obtainable through eating mandarins, and it only has a single level.
