If possible (and applicable), kill the Bull ahead of time, and do a shinecharge to gain temporary blue. Otherwise, shoot the Bull to get it out of the way; then, after getting blue speed with a stutter water shinecharge, jump directly into a spring ball jump rather than shinecharging first.

Requires:

{"or": [
  {"enemyKill": {
    "enemies": [["Bull"]]
  }},
  {"and": [
    {"not": "f_DefeatedPhantoon"},
    "canRiskPermanentLossOfAccess"
  ]},
  "canTrickyJump"
]},
"canStutterWaterShineCharge",
"h_getBlueSpeedMaxRunway",
"canTrickySpringBallJump",
"canChainTemporaryBlue"

Exit condition:

"leaveWithTemporaryBlue": {}

Unlocks doors:

{"types": ["ammo"], "requires": []}

Dev note: FIXME: Leaving with a blue spring ball bounce is possible without `canChainTemporaryBlue`, allowing a flash suit to be carried.
