WARNING: This article contains full spoilers for Loki episode 5

The thrilling fifth episode of Disney Plus show Loki showed the titular character (Tom Hiddleston) and Sylvie (Sophia Di Martino) fighting through the void to whoever is behind the TVA. Before that, however, Loki visited the league of Lokis and saw how they were living underground. During this introduction, viewers were gifted a glimpse of Throg – Frog Thor.

Throg appeared in a 2009 Marvel comic book after Thor was turned into the creature by Loki.

The joke was referenced in Loki by showing a frog version of Thor in a jar underground, right next to an abandoned Mjolnir.

This outrageous turn of events had already been detailed in 2017 film Thor: Ragnarok.

During the film, when Thor (Chris Hemsworth) ventured back to Asgard, he found Loki in charge while disguised as Odin (Anthony Hopkins).
