T-Phones

The T-Phones are an invention of Donatello the Turtles' primary means of communication when missions require them to spread out. They first appeared in episode 7, "Monkey Brains". When April O'Neil's cell phone was stolen by the Purple Dragons and eventually destroyed in episode 11 "Mousers Attack!", Donatello gave her T-Phone to replace it.

Description
All the T-Phones are shaped like turtle shells and have color schemes to match their users. They serve the same purpose as a typical cellphone, and are normally used for the Turtles to communicate over long distances. They have also extra features such as games, a camera, and a tracking app. In case of emergency, the phones are programmed to self-destruct when the phrase "T-Phone, self-destruct" is spoken.
