Shoot the block while moving up after a Space Jump; then speedball through the morph tunnel.
Entrance condition:
{ "comeInBlueSpinning": { "maxExtraRunSpeed": "$2.0", "unusableTiles": 0 } }
Requires:
"canPreciseSpaceJump" "canSpeedball"
Dev note: This can also work at much higher speeds but would be more difficult.
