Stella is a Piera. 
Stella loves trains of all kinds, old trains, cross-country jet trains, even subway trains.  Her favorite place to hang out is under the benches at Grand Central.  She finds the most interesting things there and meets the most interesting individuals.  She likes collecting information and artifacts and making them into something new.  For instance, she found an old piece of newspaper and made it into a hat and uses it as a prop to tell stories to other monsters and people she meets.  She train hops and travels from station to station to see them all and meet everyone she can.
