From all around the world, there have been many movies, TV shows, OVAs, and manga/comics where a girl grows to gigantic heights or shrinks the man they love most. Type in what you are looking for and your browser will quickly scroll to that sighting if it's on this page.
[Zatch Hunter] * Season 3: Memory of a Memory - Finn and Jake travel inside Marceline's mind, where a couple times throughout the episode, Marceline appears as a GTS.
[Light Archon] * Season 3: Dad's Dungeon - Finn and Jake go exploring a dungeon that their dad have made, which was created as a way to toughen Finn up.
]* Only Child - Tom's fed up of his sister Cindy and decides to remove her in order to be the "only child". In order that his sister reappears, he uses some magic solutions.
During one such spell, with a drawing of Cindy, Tom want to create a body for her sister, but the drawing grows and becomes a mini giantess drawing of her sister.
(orange) - The giantess is naked and you can see private parts, but only for a short amount of time (generally 30-60 seconds).
Also used if there is sexual innuendo, but no sexual acts themselves (Ultimate Girls is a perfect example).
Alas, some of the best sightings in the animated GTS world have short bits of the aforementioned material, and if the tough standards of this website were to continue, it would keep a lot of entries out of this section. Four different color-coded levels will tell you how 'safe' that particular sighting is.
That way, these 'borderline' sightings can still be rightfully told and preserved on this site, and the true hentai material (stuff that is clearly of adult/sexual nature) can still be avoided like the plague.
She created a giant pink cat called Goliad and she’s have a mind of that of a child.
