I also have more Ideas go Giant Mabel fanfics because Mabel as an adorably goofy yet gentle giantess would work as a fanfic for Gravity Falls. She's so cute as a giantess yet is clumsy and goofy, but comes as adorable and enduring at 50ft. It's a SFW Giant and Tiny fanfics too.
Also, Mabel as a giantess would wear her normal Sweater or a Sweater about her as a giant? Idk. Maybe normal Sweater works best. :3 Thanks again.
