Isobella is a Sentinel Steam Lorry who works for The Crotoonian Construction Co.
Isobella is a Sentinel Steam Lorry, an kind of old fashioned truck. She's a hard working little truck who's constantly busy shifting materials and goods about, ready to be used at the construction sites. However, she DOES care a lot about her appearance, as she does not like her paint getting sooty or mucky, making her a tad temperamental at times. She's also a little cheeky at times with the other machines, especially with the younger ones.
Isobella is based on a Sentinel DG4 steam lorry, fitted with a flatbed.
Isobella is painted yellow with red lining. She has the number "22" painted on her sides in red.
