- "I take pride in my appearance. What's wrong with that?"
- ―Isobella, Serendipity
Isabella is a valuable member of The Pack, working hard on construction and occasionally Sodor Shipping. She is close friends with Kelly, who had rescued her from falling off a bridge on a windy day.
Isabella was thrilled to see Butch after his long absence. She bid him farewell as he left for his next assignment, but she would see him again sooner than she would have expected! When Butch broke down, Isabella crashed into Butch's back bumper and gave him a nasty dent (plus a few unwanted scrapes on Isabella's fender and paintwork). Flustered, she left the very downtrodden Breakdown Vehicle be.
One day, Isabella was commended by Miss Jenny for her hard work, so she was given the task of delivering a new shipment of tools for the Pack's Repair Shed. Max and Monty were very jealous, so they began to tease her constantly. Isabella was very upset and wanted to pay them out, but Kelly assured her that patience is a virtue, and that they would get their comeuppance soon enough from natural causes. Kelly surely hit the nail on the head when Monty crashes into a pile of rubble and damages his axles! Isabella, who is not aware of this recent development, returns home with a new assortment of tools, but is suddenly bashed into by Peter Sam and skids along the side of the level crossing. She is eventually brought back on the road empty trailer'd, worried if she will be in trouble for the accident. However, Miss Jenny tells Max and Monty that it serves them right, and will have to go about the tools for the time being. Isabella, after the days events, is now a firm believer in "serendipity!"
Isabella is very concerned about her appearance, trying to avoid mud and dust whenever possible in construction. She works hard too, and is close friends with Kelly the Crane. She often tries to keep the younger machines in line, and vows to get back at Max and Monty for their ceaseless antics!
