TikTok Trend Transforms McDonald's New Milkshake into Viral Horror Sensation

McDonald's recently introduced a limited-edition purple milkshake to celebrate the birthday of their mascot Grimace.
TikTok users started filming themselves pretending to drink the shake and then showing the spilled remains with them lying motionless on the ground.
The videos are meant as a parody of social media influencers who promote brands without disclosing their financial ties.
McDonald's sees the trend as free advertising and helping to introduce younger customers to the Grimace character.
The viral moment follows previous internet crazes involving Wendy's and Rick and Morty that spread on TikTok.
