Amazing Dinosaurs for MCPE is an incredible app which includes 12 different dinosaurs in one pack. Each of them include a unique set of behaviors. For example, some of them you can tame and ride them in mcpe and others you have to be extra careful with since their aggressive behavior will make them want to kill and eat you.
There is an addon which replaces the guardians with two new aquatic animals. One of them is a “small” shark which definitely makes the underwater world a little bit more scary. The second one is a megalodon which is also a shark but somewhere around 3-5 times larger than the other. Be careful in the water!
