Plot
Amy and the kids figure out a mystery between Sonic and Tails; so they check. It's a creepy library. Against the bookshelves, they meet a cranky 102-year old guy who goes by the name of Frantz Kennel. Sonic doesn't believe what he's saying, is real. Sonic, his family, Tails and Frantz continue down a deep cave where Sonic meets up with old friends Shadow, Silver and Knuckles. Frantz tells the gang about "underground zombies" in the cave. Most zombies come for the gang and later on, Frantz sacrifices himself through flowing "underground lava". The gang runs away and back on land and they're back home.
