The acorn barnacle is a sea creature in the Animal Crossing series introduced in Animal Crossing: New Leaf.

While initially absent from Animal Crossing: New Horizons, the acorn barnacle was added in the 1.3.0 Free Summer Update in July 2020, where it appears all day long as a tiny, stationary shadow year-round.

Donating to the museum[edit]

In New Leaf[edit]

Upon donating an acorn barnacle to the museum, it can be found in the large pool in the first room of the Sea exhibit, along with many other species of sea creatures. It is found on the large rock. The exhibit has this to say about the acorn barnacle:

"They attach to hard places, and though they look like bivalves, they are related to shrimp and crab. Some species are even edible and have a very crab-like taste to them, making them a fine delicacy. Young acorn barnacles come from eggs, do not have shells, and float around the ocean like shrimp. They gradually develop their shells as they grow into the image we usually see."

In New Horizons[edit]

When donating to Blathers or selecting "Tell me about this!" in New Horizons, he will provide the following information about the sea creature:

"Do not mistake the acorn barnacle for a relative of the clam. Tut-tut, mollusks they are not. Barnacles are cousins to crabs and lobsters, you see. Though the family resemblance is hard to spot. Acorn barnacles may also seem to live a stationary life, what with being attached to rocks and such. But truth be told, baby barnacles are avid travelers, drifting shell-less about the sea before settling down. Once they find a good rock to affix themselves to, they float free no more. Which begs the question... Do adult acorn barnacles ever look out across the open sea...and long for youthful adventure once more?"

Fishing Tourney[edit]

In New Leaf[edit]

As a sea creature, the acorn barnacle cannot be scored during a Fishing Tourney, but it can still be given to Chip, who will say the following:

"Acorn barnacles are really tasty if you boil them in salt water or try to season and steam them. Ooh yeah! As for me, I'll just be eating them whole! That's just my way! YUM!"

Real-world information[edit]

The acorn barnacle, Balanus glandula, can be found from Alaska, USA to Bahia San Quentin, Baja California. They are moderate-sized with a diameter to 22mm (0.9m). The shell is formed by plates on top of each other, and they can get oxygen from air and water. They can also live up to 10 years.
