Cassie and Casey are the mascots of the keyframing development/division of Scratch 3D from 1992 to 1998 until Scratchy took their places. Cassie is a blue cat boy, while Casey is a purple cat girl. In new projects, Cassie would appear. In the European versions of Scratch 3D, Casey instead would appear. After 1998, Scratchy would appear instead of both Cassie and Casey.
