Dodging the Evirs can be tricky. Enter on the far right side, facing left, and hold left on entry to dodge them reliably.

Entrance condition:

{
  "comeInWithGMode": {
    "mode": "any",
    "morphed": false
  },
  "comesThroughToilet": "any"
}

Requires:

"h_navigateUnderwater"
{
  "or": [
    "h_crouchJumpDownGrab",
    "HiJump",
    "Gravity",
    "canSpringBallJumpMidAir"
  ]
}
{
  "or": [
    "canInsaneJump",
    {
      "enemyDamage": {
        "enemy": "Evir",
        "type": "particle",
        "hits": 1
      }
    }
  ]
}
