Sweat Punch (スウェットパンチ, Suuettopanchi) is a series of five Studio 4°C shorts collected in January 2007 as a direct-to-DVD package film titled Deep Imagination. The first four shorts had previously featured on the 4-volume "DVD magazine" series, (グラスホッパー！, Gurasuhoppa!), with one Sweat Punch episode per Grasshoppa! DVD. Upon collection and release in 2007's Deep Imagination, a fifth short was added to the Sweat Punch series. Each short is directed by a different director, and the shorts deal with a variety of subjects.
