- "Red, poisonous tadpole Noise. Stay away from their poison grip if you value your HP!"
- — Noise Report
Orchesprog has no passive capabilities.
- Poison Swarm: The Orchesprog's eyes turn red and it jumps at Neku, attaching itself to him upon contact. While Neku has any Orchesprog latched onto him, his movement is limited, losing the ability to dash along with reduced movement speed. He also takes periodic damage as long as they are latched onto him.
The Orchesprog's "Poison Swarm" attack, while not particularly damaging, will drastically reduce Neku's mobility. This can easily leave the player more vulnerable to the attacks of other Noise. Fortunately, sprog Noise have low health, so erasing them shouldn't prove too difficult, especially if a psych that affects a large area (such as Pyrokinesis) is used. Alternatively, erasing all Frog Noise will automatically erase any remaining orchesprogs.
The Orchesprog's name is a combination of "orche" (likely a shortening of "orchestra") and "sprog". "Sprog" is a UK English term for a child, and was likely chosen for its similarity to the word "frog" and since tadpoles (which sprog Noise are based on) are young amphibians.
