Easter eggs: the game's hidden secrets

Easter eggs are hidden secrets in Blox Fruits. Some are simple developer nods, others reference codes, and a few lead to real items like the Rengoku sword. The Fandom currently lists thirteen present in the game, plus one removed.

How to get it

By exploring the three seas and searching the corners of islands and buildings.

Current Easter eggs

Easter egg	Where and What
Fudd10 Sign	In the building with the Diamond chest in Lower Skylands, the ceiling has the mention "Fudd10", a reference to the troll code of the same name.
Chandler Code	A code created for Chandler Hallow, a friend of MrBeast who played the game. Probably a troll code by the developers.
Developer House	One of the houses in Middle Town opens: you find meme posters with the team, the Aura Editor, Robotmega, and a Christmas letter addressed to Wenlocktoad.
King Chad	On the base of the chess and exchange tables, a barely readable message: "chad is the king of blox fruits".
Brazil Cube	In Don Swan's mansion, a cube with Brazil's colors on the table near the bed.
Thailand Ball	Also in Don Swan's place, a ball with Thailand's colors on the neighboring chair.
Vietnam Cone	Behind one of the mills near the Mansion in the Third Sea, a cone with the texture of the Vietnamese flag.
Dog House (Wenlock)	Wenlocktoad's doghouse, next to Arowe in the Second Sea and in a ruined house on Floating Turtle in the Third Sea. This NPC seriously sells a physical Rocket fruit for 97 Robux.
Dog House (Indra)	Nicknamed "xindra_tentashun", it's the very first NPC in the game, created to test the dialogue system. It's now part of The Son Quest.
King Toad's House	Next to the Cafe's Awakenings Expert, a glitch allows you to pass through the closed door. Inside, all-green and messy frog furniture, in memory of when Wenlocktoad lived there.
Rengoku	By defeating the Awakened Ice Admiral or all enemies in Ice Castle, you can obtain the Hidden Key. It opens a room behind the castle's stairs, where a chest gives you the Rengoku sword.
Gravestones	Some gravestones in the Graveyard have messages that look like obituaries. These are developer jokes.
Life Form and Undead	Two hidden messages, one behind a pillar in the awakening room, the other in the Cyborg race purchase room. Both announced the Slayer Skin before its release, and recall that it only requires races obtainable from Tort.
Light Raid Poneglyph	On the last island of the Light raid, a Poneglyph similar to those that were removed, inside the temple.

The Fudd10 message written on the ceiling, inside the building.

The entrance of the Lower Skylands building hiding the Fudd10 message.

Removed Easter egg

Before Update 12, two Poneglyphs were in the Second Sea: one on the small unknown island and one on the shore of Snow Mountain. They have been removed since.
