Bill and Ben

Description
Bill and Ben were yellow 0-4-0 saddle tank engines. Their faces were mutated due to the explosion. They somehow reached the docks and found BoCo, but were slaughtered after asking him for help.

The effects of the mutation was similar to Thomas, where they seemed sadder, but still acted the same. They were at Brendam Docks, hiding from the armed men. When they saw BoCo, they came out, trying to ask him for help. However, BoCo was immediately frightened by their appearance, and yelled in fear, which drew the attention of the armed men. BoCo realized his mistake and told the twins to run, but their mutations made them move slowly. The armed men were easily able to catch them, and kill them.
