Dolphin Spawn Egg is a Creative-mode item that spawns a live dolphin (minecraft:dolphin) the instant it is used on a block, introduced in Java Edition 1.13 and Bedrock Edition 1.5 as part of the Update Aquatic. Dolphin Spawn Egg cannot be crafted, found in loot, or obtained in Survival — it appears only in the Creative inventory or through the /give command. The egg uses a teal base with light gray spots that mirror a dolphin's own coloring, making Dolphin Spawn Egg easy to pick out from the other aquatic spawn eggs.

Players use Dolphin Spawn Egg to populate oceans, rivers, and hand-built aquariums without waiting for natural spawns, which occur only in non-frozen ocean biomes. A spawned dolphin follows boats, plays with floating items, and grants the Dolphin's Grace status effect to nearby swimmers, increasing swim speed. Feed the dolphin raw cod or salmon and it swims toward the nearest shipwreck or ocean ruins, so Dolphin Spawn Egg is a quick way to set up treasure-hunting demos or themed water builds on a map.
