- Hush-Bats (debut)

- Yōkai Kids (Maurice LaMarche and Rob Paulsen) (debut)
- Donnie: But Raphael, a library is a treasure hunt. You never know what gems you may find along the way!
- Donnie: What? Would a child have a platinum library card? Would a child have won the national library competition 3 years in a row? Would a child be an expert on Dewey decimal mathematics? I can divide by biographies!
- Mikey: *sharp inhale* ECHO! I REGRET NOTHING!
- A few Easter eggs relating to the Turtles' Renaissance-era namesakes are briefly seen when Donnie explains the "sum knowledge of entire civilizations".
- The phrase "New toy!" said by a Yōkai kid, then Mikey, is a reference to Disney/Pixar's Toy Story 3 when a Jack-in-the-box says the same phrase whenever a new toy arrives at Sunnyside Daycare.
- Donnie's library rap was written to match the rhythm of the rap track from the 2012 TV series theme song.
