Giraffes in the Savanna, Otters & Platypuses in the Swamp, and Monkeys: 1

Giraffes are animals that live in the savanna and the savanna plateau. Giraffes are 5.5 blocks tall and babies are 3.5 blocks tall. These guys, like horses and llamas, are tameable and can be ridden. How can you tame/breed them you ask? Well, if you give two giraffes acacia leaves then they will breed. If you give a giraffe ten leaves while shifting, you can tame one.
With your giraffe, let's go to the swamp where otters and platypuses swim and crawl. Otters are 1.5 blocks long. They can be bred with cod/salmon and tamed with a cod/salmon in a bucket. Tamed otters are like wolves that can swim. Platypuses are as long as otters. These guys can be bred and tamed with one thing: worms. Worms are a new item found anywhere with dirt. You can catch them by digging deep or catching them with a bucket when it rains. Platypuses can be bred with a bucket of worms, yet taming them is a pinch harder, cider worms. Cider worms are in cider pools in the wetland. The bucket of cider worms is aggressive mobs. If you put worms in the cider pools, they need a minute to turn cider worms.
