1. Blue axolotl

/summon minecraft:axolotl ~ ~ ~ {Variant:4}

The blue axolotl only appears from breeding, and very rarely. Variant sets the color: 0 lucy (pink), 1 wild (brown), 2 gold, 3 cyan, 4 blue. Summon it in water so it does not dry out.

2. Axolotl in a bucket

/give @s minecraft:axolotl_bucket[bucket_entity_data={Variant:4}]

Release it anywhere you like (1.20.5+ syntax).

3. Brown panda

/summon minecraft:panda ~ ~ ~ {MainGene:"brown",HiddenGene:"brown"}

Brown is recessive, so both genes must be brown. Other genes are lazy, playful, aggressive, worried, weak and normal.

4. Pink sheep and brown mooshroom

/summon minecraft:sheep ~ ~ ~ {Color:6b}
/summon minecraft:mooshroom ~ ~ ~ {Type:"brown"}

Color 6 is pink. Brown mooshrooms normally only appear when lightning strikes a red one.

5. Killer bunny

/summon minecraft:rabbit ~ ~ ~ {RabbitType:99}

A hostile white rabbit with red eyes, only available by command. It does not appear on Peaceful.

6. Frog variants

/summon minecraft:frog ~ ~ ~ {variant:"minecraft:warm"}

Frogs come in temperate (orange), warm (white) and cold (green). For wolf and cat variants, see the tame pet command.
