The Castle of Dr. Blokanitch Part 1 is the 14th episode of Pooh's Adventures Treasured Tales.
Taking place right where Pooh's Adventures of Total Drama All-Stars left off, Winnie the Pooh, Ash Ketchum, Bloom, Simba, Littlefoot, their friends, and the villains (along with Zoey, Mike, Gwen, Cameron, Owen, Heather, and Alejandro) get lost in the middle of the ocean, and are eventually founded by a man named Dr. Blokanitch, who (along with his servant Wretchworth) invites our heroes and villains in his castle to make themselves comfortable. Little did they know that the doctor has a nefarious scheme on his mind.

- The 2-part episode will be based on Uranimated18's fan-fiction story on DeviantArt called TDAS: What Happened Next?.
- Much like in Pooh's Adventures of Total Drama All-Stars (and the previous Winnie the Pooh/Total Drama projects that will be made before that crossover project), the guest villains will be helping Heather and Alejandro in this 2-part episode. This is because RatiganRules believes they can still be villains at heart.
- The storyline continues in The Dreadful Castle of Dr. Blokanitch Part 2.
