So when adult Sasha picks up adult Marcy, Marcy has a birthday bag for Anne, showing that it was Anneâs birthday. On the TV, there is a news cast stating that it has been exactly ten years since âFrogvasionâ. This means that âFrogvasionâ was exactly one year after the trio arrived in Amphibia as they entered on Anneâs birthday. This also means that if Anne, Sasha, and Marcy were 13 when they entered Amphibia, they would all be 14 by the finale. This means that when the Three Stones Deity says that Anne is 13, it was wrong.
