The result of Crackitus's successful experimentation in the field of "Cold Steam" the Cryo-One uses a ectoplasm fueled cold steam reactor to create a mass of extremely low temperature gas. The gas projector is used to direct the flow of icy cold onto the target. 
 
The end result is a target rendered immobile by a shell of ice and reduced to a state of sleepy torpor by the chilling cold. This allows the subject to be safely transported* to the League's Lab or relocated to a new home where both creature and public will be safe.

*It is key to avoid sudden impacts and drops as the subject is rather fragile at this point.
