She only appears in the episode, "Grammy," but is mentioned sporadically throughout the rest of the series, along with Trevor. In "Grammy," she pays a visit while Walter and Audrey are out for the weekend. She doesn't seem to like Drake that much, like she does with Josh. Grammy makes a bet with Drake, that if Grammy loses a basketball game to Drake, he can go out with his friends but not to the concert, but if Drake loses, he can't go out. Despite her disdain to Drake, she does have compassion for him; as she let him win the basketball game so Drake can hang out for the night, doesn't tell Audrey and Walter about the concert, and lets Drake keep the money he owed her after she bailed him out.
In "The Bet," Grammy is mentioned when she sent Josh a GameSphere, but Josh is unable to play it due to the bet he made with Drake, in which who can last the longest without giving in to their habits. She was last mentioned in "Tree House" as well as in Merry Christmas, Drake & Josh.
