Birthday Song

Birthday Song is a task advancement in the Husbandry tab of Minecraft's advancement system, carrying the in-game description "Have an Allay drop a Cake at a Note Block." It branches directly off You've Got a Friend in Me, 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. Birthday Song was added in Minecraft 1.19, from The Wild Update, 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, Birthday Song sits second along its line: the full path from the Husbandry root reads Husbandry -> You've Got a Friend in Me -> Birthday Song. That means 2 advancements must be completed before this one becomes available, and Birthday Song is one of 31 total advancements in the Husbandry tab. No other advancement shares its parent, so it is the only thing that branches from You've Got a Friend in Me.

Birthday Song 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.
