Each piece of food has approximately a 10% chance of taming it.

A tamed Tyrannosaurus keeps the same owner when it grows into an adult.

Mammoth Inventory
An adult tamed Mammoth has its own inventory with:
27 slots — 3 rows of 9
To open it:
Be in Survival Mode.
Mount your adult Mammoth.
Press the key configured to open your inventory — E by default.
The storage:
belongs to the Mammoth itself;
remains saved after closing the world;
persists after the chunk is unloaded;
accepts items and tools normally;
supports quick item transfer with Shift + Click;
drops its contents if the Mammoth dies;
does not dismount the player when the interface is opened.
When mounted and moving, the Mammoth also breaks leaves blocking its path. Logs, structures, and other blocks remain intact.
Plesiosaurus
A large aquatic predator designed to behave like a true marine creature.
Health: 40 points — 20 hearts
Base Damage: 7 points
Normal Swimming Speed: 1.20

Habitat: oceans
Has three adult variants with scales of 1.50x, 1.75x, and 2.00x
All babies have the same size
It can spawn in normal, deep, cold, lukewarm, warm, and frozen oceans.
Aquatic Behavior
The Plesiosaurus:
swims and explores in all directions;
rises toward areas near the surface;
dives into deeper waters;
rests between exploration periods;
hunts occasionally;
chooses one target at a time;
has pauses and cooldowns between hunts;
may consider any living creature in the water as potential prey;
can attack swimming players.
Outside the water, it remains motionless and uses its surface animation. It does not walk, jump, or attempt to fly back toward the ocean.
How to Tame
Only Baby Plesiosaurus can be tamed.
Use:
cod;
salmon;
tropical fish.
Each fish has approximately a 10% chance of taming it.
Once tamed, the Plesiosaurus can follow its owner underwater and defend them or attack targets selected by the player. It will not follow its owner onto land.
Wild adult Plesiosaurus cannot be tamed, and the species cannot breed using food.
