The developers have prepared many new models.
Minecraft developers have released a major update 26.1 Tiny Takeover. New cute models have appeared in the game.
Mojang Studios has introduced mob babies — they can be made eternally young with the help of "Golden Dandelions" (crafted from flowers and gold nuggets):
Collect babies, fight with them, give them names, or leave them as babies forever, but remember that a cute face is not necessarily friendly!
Also introduced "Music Block: Trumpet":
Place a copper block under the music block, and the sound of the trumpet will change as the copper oxidizes! If you don't want the sound of the trumpet to change over time, rub the copper block with wax.
A full description of the Tiny Takeover update for Minecraft is available at the following link.
