Tyler and Tina the Teenagers first appeared in Diner Dash Hometown Hero. They're impatient when they're in line and at the table. They annoy other people at the table when they talk through their cellphones at the table. But if the Teenage boys are seated to a table next to the Teenage girls' table, they stop talking through their phones and flirt with each other. It would not only stop annoying the other customers but makes the teenagers happier.
In the levels when their patient and happy, their eyes are shut but when they get impatient, their eyes are opened. They also open their eyes when they're flirting with each other or when they're starstruck.
In Fitness Dash, only Tyler appeared in Jo's Gyms. Tina was also implied to be really strong which could explain why we don't see the teenage girls in
In 'DinerTown Detective Agency', Tyler worked as an intern in Big Corp. When Tina and Tyler were competing with each other for High School class President, Tyler said that Tina's 'lame' because she beat him which could imply that they have a love/hate relationship.
In Avenue Flo, Tina worked as a first floor secretary in Mister Big's building and her relative works in the highest floor next to Mr. Big's office door. In Avenue Flo Special Delivery, Tina sold snow cones at the park in Yum Yum Square. Tyler worked at the Baby Craze superstore. Tyler seems to adapt the carefree and lackadaisical personality.
Tina appeared in a cameo at the start of 'Fashion Dash'.
Tina also (along with Rosie Regular) stands up for animal rights, although some of the teenage girls (particularly the ones from Champagne Falls) aren't limited to eating Muscovy Duck.
Some of the Teenage Girls live in Bistro Bay, while the others live in the most richest part of DinerTown, Champagne Falls. Some of the Teenage boys live in Squid Row, while others seem to live in the Fame themed, Thyme Square.
They also seem to like seafood such as Bistro Bay Squid, White Shrimp, Jumbo Bay Shrimp, Ahi Tuna and Sergasso Seaweed.
Although some of the Squid Row teenage boys would still go to Darla's Sidewalk Cafe, more of them would go to Cowboy Jack's Wrangler Restaurant for the meals with the Jalapeño Peppers, Meyer Lemons and Meatropolis Ranch Chicken. In Thyme Square, they seem to like anything with Organic Red Potatoes, Finest Imported Dough and Heirloom tomatoes.
