Buenos Y Míticos Días

Buenos Y Míticos Días is one of the two spinoff channels of the daily morning web series, Good Mythical Morning. It consists of some GMM episodes in non-chronological order that were dubbed into the Spanish language. It currently follows a weekly uploaded schedule, with new Spanish-dubbed episodes being uploaded every Monday.

Overview
The channel traces its roots as an April Fools joke in 2015, where viewers were greeted to a video on the main channel that was entirely dubbed (including the title and the descriptions of the video) into Spanish, named "7 Last Minute April Fools' Pranks" (Spanish: 7 Bromas para el Día de los Inocentes).

Most likely due to public demand, a Spanish-dubbed version of GMM began uploading episodes on May 18, 2015. Unlike the original channel, they were episodes of the show that were already uploaded on the main channel as part of Season 7. Some of the videos were from past seasons which are grouped together in a playlist titled "Best of GMM". The final episode was uploaded on July 30, 2015 with the episode, "Talking House Experiment" (Spanish: El experimento de la casa parlante).

The channel became dormant for a few years until the channel was revived on June 28, 2021 with the Season 19 episode, "Do These Foods Taste Different In Other Countries?" (Spanish: ¿Estos alimentos, saben diferente en otros países?).
