Mochila is the Spanish word for backpack and the name of Dora's talking purple backpack in Nickelodeon's animated series Dora the Explorer, which premiered in 2000. In episodes, Dora sings the backpack's name to summon it, and Backpack then opens to reveal the tools she needs for her adventure. The simple call-and-response chant became familiar to young viewers who watched the show regularly. As that audience grew up, short clips resurfaced in nostalgia edits, reaction videos and meme compilations, keeping the cheerful phrase recognisable to a new generation.
