Enter on the right side of the transition and move left to avoid damage.

Requires:

"canPrepareForNextRoom"
"canPlayInSand"
"canTrickyJump"
{
  "or": [
    "Gravity",
    "HiJump",
    "canInsaneJump"
  ]

Dev note: Entering from a non-sand room makes the suitless+hijumpless dodge only possible with a walljump. Entering through the Toilet does not affect this dodge strat much.
