Trivia

 * According to an interview, the reason that Splinter looks like he's gained a few pounds, is because since there's no Shredder in the new series, Splinter has no exact reason for training the turtles, however after they learn about threats, such as Baron Draxum, he begins training the turtles more seriously.
 * Splinter's weapon of choice is jokingly listed as the "TV remote" on his bio.
 * According to his bio, Splinter was human before being turned into a rat.
