Cacto Hipopotamo belongs to the Italian brainrot wave that spread on TikTok in 2025, where AI generated hybrid animals were given rhyming Italian style names and dramatic voiceovers. This character mixes a hippopotamus with a cactus, placing the creature in a desert setting for extra absurdity. Clips and sounds linked to the trend were reshared as short edits, remixes and soundboard posts, with Spanish searches for hippo sounds also leading viewers to it. Its appeal is the nonsense lore and instantly recognisable name.
