VidCon is a convention for YouTube, its creators and fans, held annually in Southern California since 2010. Poppy has performed at VidCon twice. She first performed at VidCon 2012 with HeyHiHello and other internet personalities during her "Moriah Poppy" era, and performed again at VidCon 2019.
She performed a cover of MGMT's song "Kids" with HeyHiHello.
Poppy performed a DJ set with Charlotte and was originally going to sing "Scary Mask", but her performance was ultimately cut short due to going over the allotted time.
Charlotte officially released the instrumental to the 2019 DJ set on SoundCloud.
This instrumental contains the acapella from "Lowlife" and an edited version of "Scary Mask".
