True Ending Glitch?

[Leeaux]

Hey guys, Just curious and I can't find an answer online. I helped all the puppets

-Got Pearl's eyes
-Comforted Gobblette
-Helped Ray fix the Pipe
-And did the duet with Arnold.

But I didn't get the good ending, I've even got the achievements for these. So I guess I'm either missing something that actually gets the ending or the game just glitched? Anyone have any ideas?

Did you feed the dogs?

LEF - I think I figured it out, I did give Pearl the glasses but I didn't speak to her afterwards.
