Bounce into the spikes and use a speedkeep to run on spikes to setup for a speedball towards the item. A damage boost speedkeep could be used instead of a spike speedkeep with enough runspeed.

Entrance condition:

{
  "comeInRunning": {
    "speedBooster": true,
    "minTiles": 4
  }
}

Requires:

"canSpeedKeep"
"canCarefulJump"
{
  "getBlueSpeed": {
    "usedTiles": 21,
    "openEnd": 2
  }
}
{
  "spikeHits": "n_speedKeepAttempts"
}
{
  "or": [
    {
      "spikeHits": "n_speedKeepAttempts"
    },
    {
      "and": [
        "canChainTemporaryBlue",
        {
          "spikeHits": "n_speedKeepLenience"
        }
      ]
    }
  ]
}
"canSpeedball"

Dev note: The extra lenience is because of the need to either to perform a very precise jump off the spikes, or to start with a bounce on the spikes, taking an extra hit.
