==When Used==
*''From inventory, first use:''
{{useitem|
text=You head down the ladder into the Bat Hole and break open the sonar-in-a-biscuit. Deafening waves of sound echo throughout the Hole, and the wall of rubble leading west from Guano Junction collapses in a heap. Er... a smaller heap than before.}}

*''From inventory, second use:''
{{useitem|
text=You head down the ladder into the Bat Hole and break open the biscuit. This time the sound waves knock down the pile of rocks on the east side of Guano Junction.}}

*''From inventory, third use:''
{{useitem|
text=You climb down the ladder into the Bat Hole, situate yourself in front of the last remaining pile of rocks, and break open the sonar-in-a-biscuit. The high frequency noise makes short work of the rubble.}}

*''From inventory, after the first three times:''
{{useitem|
text=There's nothing left to do with these. They're probably still useful in combat, though.}}

*''In combat:''
{{useitem|
text=You crack open the biscuit, and waves of sound wash over your opponent, doing 5-7 damage.|
type=combat}}

*''From inventory, during a [[Grey Goo]] run:''
{{useitem|
text=You have no idea what to do with this thing...}}

==Uses==
*[[squeaky staff]]

==Notes==
*Formerly required in order to defeat the [[Bowling Cricket]] in [[The Sorceress' Tower (The Stairs)|The Sorceress' Tower]].
*The first sonar-in-a-biscuit successfully used in an ascension will open the [[Batrat and Ratbat Burrow]].  The second will open the [[Beanbat Chamber]].  The third will open [[The Boss Bat's Lair]]. 
*Killing a [[screambat]] while [[The Bat Hole]] is open will have the same result as using a sonar-in-a-biscuit.
