Sally Mouse and Cassie Cat are the best of friends. 

Sally decides to make Rice Krispies treats with unicorn marshmallows. She knows they are one of Cassie's favorite treats and wants to show her that they are cherished friends. She makes them special by using her favorite unicorn cookie cutter. 

She and Cassie like to share treats and have silly conversations as they enjoy each other's company. 

Sally has made a unicorn-shaped purse for Cassie as a special surprise. 

They decide to have a tea party to share their treats on Friendship Day. They have so much fun being silly together. They enjoy sipping hot chocolate with mini marshmallows and telling stories. 

They have so much in common which makes their friendship so neat.
