Uh Oh

Uh Oh is a task advancement in the Husbandry tab of Minecraft's advancement system, carrying the in-game description "Have a Sulfur Cube absorb a TNT block." It branches directly off Husbandry, so that earlier advancement is its prerequisite and must be earned first. The Husbandry tab covers advancements related to farming, animal breeding, food, and the natural world. Uh Oh was added in Minecraft 26.2 and is still in the 26.2 advancement set.

It is rated Medium difficulty on this site: requires some preparation or specific resources. Part of normal gameplay progression. It uses the standard task frame, meaning it is a normal step in the tree rather than a goal or challenge milestone. Nothing else in the tree depends on it, so it is a leaf at the tip of its branch.

In tree terms, Uh Oh sits first along its line: the full path from the Husbandry root reads Husbandry -> Uh Oh. That means 1 advancement must be completed before this one becomes available, and Uh Oh is one of 31 total advancements in the Husbandry tab. It shares its parent with 12 sibling advancements (Bee Our Guest, The Parrots and the Bats, Best Friends Forever, A Seedy Place, Fishy Business, Glow and Behold!, Whatever Floats Your Goat!, Total Beelocation, Bukkit Bukkit, Smells Interesting, You've Got a Friend in Me, and Stay Hydrated!), all of which open from the same point in the tree.

Uh Oh grants no experience directly; its value is progression rather than a point payout.

It is a leaf advancement, so nothing further unlocks from it; it stands as a completed tip of its branch.
