Minecraft Dungeons:Baby Ghast

"Nothing to cry about here, this Baby Ghast is the best pet ever. Just watch out for accidental fireballs."

- In-game description

The Baby Ghast is a pet mob $$ obtained through the Flames of the Nether DLC, Ultimate Edition, Season Pass, or the Ultimate DLC Bundle. It is purely cosmetic and does not attack enemies.

Appearance
The Baby Ghast is a juvenile form of the ghast. They are characterized by having small white translucent bodies with a red core inside, a small mouth, red eyes, and small tentacles. The whole body of the Baby Ghast is smaller and almost the size of the hero's head, and it also disappears when the hero is away and appears when they are close, making it similar to a ghost.

Trivia

 * The description claims it shoots fireballs accidentally, but does not do so in game.
 * Despite this, in a Twitter video, the baby ghast is seen launching a small fireball at the Village Merchant.
