Sprayground joins forces with Nickelodeon's SpongeBob SquarePants to create the Doodle backpack, referencing the "Frankendoodle" episode from the show's prolific second season. The bookbag features Doodlebob holding the Magic Pencil, accompanied by the brand's signature shark motif.Outfitted with high - quality materials, the bag is designed with a roomy main compartment, an internal padded laptop sleeve, velour-lining, and a multitude of variously-sized, zippered pockets to keep all items separated and organized.
