Thomas the Tank Engine is on the spotlight in Sekiro: Shadows Die Twice. Thanks to Nexus Mods user, Katalash, the popular train made a cross over to the action-adventure video game of FromSoftware.

Thomas is the new face of the Great Serpent. The mod was called “Thomas the Snake Engine,” and the train has retained his whistle. Players cannot hear the popular Thomas tune though.

All the players can hear is train’s whistle as he floats around Sekiro. Thomas in Sekiro game is the latest addition of the modding community on the reimagination of popular video games.

The Great Serpent is actually one of the bosses in Sekiro which players will encounter several times. It can be seen particularly in the Ashina Outskirts.

The Great Serpent would usually appear once the game level is about to end. This means players can chance upon Thomas the Serpent in the game several times.

Some gamers described Thomas’ grin as “unnerving.” Thomas does not blink, and he appears ready to hit Sekiro any time. His whistle can be heard too before he finalizes an attack.

However, it’s a bit disturbing to find Thomas reeling back and flailing about when he performs the deathblow. His painful whistle is also uncomfortable to hear.

This is not the first time that modders used the friendly train. Some of the amazing mods created with Thomas this year included those from Skyrim and Resident Evil 2.

Just this January, Thomas became the reincarnation of Mr. X in the remake mod of the Resident Evil 2. The modder apparently used the creepiness of Thomas’ grin and his bulky engine body.

Instead of a Mr. X throwing his punches, players saw Thomas hitting them with his body and shoulder.

In 2013, a Skyrim mod also turned the dragons in the game into Thomas the Train Engine. Called the “Really Useful Dragons Mod,” the Elder Scrolls 5: Skyrim game also featured Thomas whistling.

To try it out, players can install the mod through the Sekiro mod engine. Once the Sekiro mod engine is installed, players can head to Nexus Mods.

It should be easy to find the Thomas the Snake Engine mod page there. After which, the mod file should be extracted and copied to the mods folder.

Sekiro: Shadows Die Twice is available on PlayStation 4, PC, and Xbox One.
