Bad Piggies is a puzzle game released by Rovio in 2012 as a spin-off of Angry Birds, putting players in control of the green pigs instead of the birds. Instead of launching birds, players build cars, planes and other contraptions from parts to reach a goal, often with spectacularly unstable results. That building-and-crashing gameplay made short clips from the game popular in gameplay videos and memes, where the cheerful theme became shorthand for a clever idea going wrong. It remains popular because that joke still fits almost any DIY fail.
