I know some episodes that are remakes of episodes from the original Blue's Clues have a bit of negative continuity, but I feel that the following episodes need "Blue's Clues & You!" remakes:
1. What Was Blue's Dream About?
2. What Did Blue See?
3. What's That Sound?
4. Signs
5. The Wrong Shirt - It was once rumored that this episode would get a remake.
6. Words
7. Blocks
8. Rhyme Time
9. Puppets
10. The Boat Float
11. Shape Searchers
12. Contraptions!
13. The Alphabet Train
14. Numbers Everywhere!
15. Meet Polka Dots!
