The Hourglasses are three souvenirs in WarioWare: Twisted!, located in the Doodads folder. They are used to tell the time, accomplished by rotating the console and letting the sand drain from one bulb to the other until nearly none of it remains. They differ in the quantity of sand they contain.
The Minuteglass contains yellow sand, and it empties out in approximately a minute.
The Ramen Timer contains blue sand, and it empties out in approximately three minutes.
The Egg Timer contains red sand, and it empties out in approximately five minutes.
