Mines chapter

Thomas

A Thomas the Tank Engine on spider legs. He is the game’s second monster, not an easter egg — the developers sell a game pass for the chance to play as him.

Why one player calls him easier

A player who has cleared both the School and the Mines gives a specific reason rather than a vague one — “Thomas is way bigger. You can hear his music from way farther, and he doesn’t teleport on top of you like somebody else.” Both of those give you time to react, which is the difference they are pointing at. Not everyone agrees on the teleporting, though: other players say he does.

Walls and teleporting

The walls are the less disputed half: “He went through the wall. I was under the table.” and, a moment later, “if you uh go under the uh little crawl space, he just goes through the wall.” A separate recording, mid-run: “Look, he’s going through the walls.”

Other players say he does teleport. Elsewhere in the same recording: “And yeah, he does teleport.” Earlier in that same run the call was less certain: “Either go through walls or he’s teleporting”. A second recording has the shout “He just teleported.” and, a few minutes later, “He just came all the way back to spawn and almost killed me.” Looking back at the end, one of that group says “whenever he spawned on you or like he spawned on us”. A third recording: “Spawned in behind me.” and later “Bro, teleported, bro. Teleported.”

Whether he lands right on top of you is still disputed, but those reports have him turning up back at spawn, behind a player, or on the group, so do not lean on his music alone — that same third recording has that too: “I didn’t even hear him until he was right behind me.”

You can be Thomas

In Hide And Seek one player is drawn as the monster each round, and the store sells passes that double your odds of being picked: one for the Cat, one for Thomas, since Update 2 one for Ronald, the Play Place hunter, and since Update 3 one for Bon Bon.

Free Roam goes further: the VIP pass grants :spawn Cat and :spawn Thomas, once per server, and a spawned monster sticks around for 90 seconds.

Still open

Is any room safe from him? One group plays as if some are: “we have a safe room. Thomas the train cannot reach us while we are in this safe containment quadrant.” Later in the same recording: “I’m pretty sure we’re safe from him in this room, though.” That is one group’s read. With the wall reports above, it is not worth betting a life on.

The hold-breath prompt. Official art for the Mines shows a player crouched behind a crate with both hands over their mouth and an E — HOLD BREATH prompt on screen, with Thomas coming up the rails. The official control list does not mention E, so treat the prompt as art that may be ahead of the build rather than a mechanic you can use tonight.
