Clear the bomb barriers and farm two Wavers. The two side wavers are local and easier to position for the R-Mode Spark Interrupt. It can help to pause abuse in the acid either to damage down or as part of the R-Mode Spark Interrupt. If grabbed by a Yapping Maw during a Shinespark, keep at least any button held to prevent a crash.
