When Belle first arrived on Sodor, she helped Thomas and Percy put out a fire at an old farm shed. Belle later advised the Fat Controller to bring Flynn to Sodor. When the Sodor Dieselworks was on fire, Belle and Flynn put out the fire just in time. Belle later tried to befriend Toby when she learned that they both had bells. At first she did not understand that Toby was an older engine that may not like the same things she does, but she soon realized her mistake and they are now firm friends.
