bottle on B setup, break grass
catch the bugs on B w/ hookshot c-right
equip ice arrow bugs c-right, then equip swap stick over ice arrow bugs c-down (puts empty bottle on c-right)
bait butterfly, shield swipe fairy on B
equip poe c-right, shield swipe fish on B
leave grotto

Alternate grotto rba if we want 29 chus instead of 25:
catch bugs on B w/ hookshot c-right
equip poe c-right, shield swipe bugs on B
equip ice arrow bugs c-right, then equip swap stick over ice arrow bugs c-down (puts empty bottle on c-right)
bait butterfly, shield swipe fairy on B
equip lens c-right, shield swipe fish on B
This is one more pause and catch and shortens hammer pot chest opening.

js clip to dmt
equip hookshot c-down, egg c-right
get bombs
begin SRM by dropping B fish (w/ egg c-right)
