The Milkshake Academy is a facility that appeared in the episode "License to Milkshake." It serves as the main setting for that episode.
The Milkshake Academy is where people go in order to learn how to make milkshakes sucessfully and be able to serve them out as well. It is run by Captain Frostymug who has been milkshaking for twenty years. After one or many has passed all of the tests, they are awarded Milkshake Licenses giving them permission to make and sell milkshakes.
The Milkshake Academy from the outside in incredibly huge. It was many glass windows and a giant replica of a milkshake at the very top. Also on the outside, huts can be seen where cadets may sleep in. It also has a beach seen somewhere close by. And this is also where cadets do air training.
Like the outside, the inside of the Milkshake Academy is pretty huge as well. It has many rooms, through, only a few are explored in License to Milkshake. It has a room where the cadets, and SpongeBob, operate machines to blend milkshakes. It also has another room with a machine where Captain Frostymug test people on how to "be a shake." It is called the Shake Simlator. Only SpongeBob has been seen in there. The academy finally has a room where Frostymug awards cadets that have successfully made it through the courses and hands them their Milkshake Licenses.
