Ms. Hickory teaches Piggy how to play the piano.
Ms. Hickory is a piano teacher featured in the Muppet Kids book Piggy Gets the Jitters.
She gives Piggy piano lessons and counts out the beats as Piggy plays. Ms. Hickory hosts a piano recital at her music studio. Piggy is initially nervous about performing in public, but after she completes her piece Ms. Hickory congratulates Piggy for her hard work and determination by saying, "I'm very proud of you, Piggy. You gave a lovely performance."
Rowlf is also one of her students and plays in the recital as well.
