Final oc. A road vehicle. And if you've read the replies on my most recent post you may already know about her.
Boba! The bus. She's a sweet, privately owned bus who works both with the railway and the sodor construction company. She's a hardworking bus, and specialises in transporting workmen to jobs around the rails and whatever the pack is working on. Alongside that she is completely mute, and relies on morse code (with her headlamps) and her horn to communicate. Despite how she may appear she can be quite spicy, sassing humans and engines alike when she feels insulted by them. Though she is a sweetheart with those she likes. Still completely willing to let her friends crash and burn and will only help with picking up the pieces.
Human and monster engine form.
And as a bonus image, a nice family portrait. Shout out to @gronkgal for correctly guessing all the bus children.
As can be seen, bertie is her mate. Their children take some elements from one parent or the other. Betty is exactly like her father, byrons a bit of a shy one, Bella is a sweet but brutally honest girl, and Brandon and bernie are still too young to be anything more than a pair of cute and curious boys.
