Wormcore, also tagged as Worm Time, is variation of toywave based on the toys known as Worm On A String, Magic Worm, and Squirmles. Worm Rights may also be tagged when the post has LGBT overlap. This aesthetic is theorised to have started from the Furby Fandom on Tumblr, as members of Furby Fandom often joked about Squirmles being a Furby's food. The phrase "Oh, worm?" became a Tumblr meme in early 2017, thus bringing the first wave of site-wide attention to the worm toys. Wormcore emerged as its own subculture in mid to late 2019.
