Several PBS Kids shows share a universe with several Sony-produced animated shows including Men in Black: The Series
This was discussed on the WMG page for Sesame Street as part of a larger theory also detailed on WMG pages for Men in Black: The Series, Dragon Tales and DiC Entertainment's shows in general. In addition to Dragon Land and Max & Emmy, the MIB (in the cartoon-verse) keep tabs on Mister Rogers, the Neighborhood of Make-Believe, and Someplace Else, they've dealt with Hacker, they've gone to Sesame Street and met the residents there, have investigated rumors of four dinosaurs residing in a small Dallas-Fort Worth park, they've met Theo & Cleo Lion, have learned of the existence of a human-like alien residing on Earth, keep a tab on The Cat in the Hat, have visited Shining Time Station and met with Mr. Conductor, they've investigated the existence of Animal Junction and keep tabs on the Kratt brothers and Zoboomafoo, they have learned of the existence of The Magic School Bus, keep tabs on Animalia, and also investigated rumors of a gigantic red dog living on Birdwell Island.- For that matter, they're also pretty suspicious of the Hero Elementary School, have personally assisted in the genetic mutation of the animals seen in Let's Go Luna!, Nature Cat, Arthur, and Elinor Wonders Why so that they can talk and act like humans, helped develop the Secret Museum, founded Odd Squad as an MIB for kids, and have dealt with the Wild Kratts Rogues Gallery.
- They don't really check on Qyah because nothing odd or supernatural really occurs there, but they do know the Mabray family. They do keep tabs on Caillou and Pinkalicious so they don't get steered down the wrong path when they grow up.
- The Secret Museum's existence is also why Peg and Cat regularly meet up with famous people of history like Cleopatra, Beethoven, George Washington, and Albert Einstein.
- They also tried to genetically modify the fish seen in Splash and Bubbles, but only gave them the ability to talk. They genetically modified the residents of the World Tree, but couldn't get them to wear clothes.
- They are good friends with WordGirl and keep tabs on the Super Readers, the Wordfriends, and Martha.
- They made the alphabet soup that gave Martha the ability to talk.
- They personally fund Sid's school, developed Maya's glowing hair bobbles, check up on Curious George, and keep tabs on NODDY's.
