Deema's Seashell Store is the Shop Segment from the episode: The Beach Ball!
Gil and Bubble Puppy wish to buy seashells and they go to Deema's shop where she informs them she is having a special on matching shells. Gil and Bubble Puppy can have any seashells that look exactly alike. Gil sees two matching blue shells and then two purply-blue conch-like shells. Gil thanks both Deema and the audience for help.
