Um...
Var Float (Number with 6 decimal places)
Var Int (Non-decimal Number)
Var Bool (Yes/No variable)
Var Class (Selects a class type for the variable)
Note: Usually, after the Class bit, people put things like <Decoration> or <Weapon>, this limits the choice for this variable to things from that class.
Var YourClassHere (Lets you play around with the properties of another class, usually to do stuff like change appearence, etc.)
Note: Where YourClassHere is, put any class you like, so long as it has lots of variables to play around with
Var String (Text entry variable, can be used for messages, or commands)
There is a Var Enum or something, but i dunno how to explain that one..
Finally, if you put () after the Var bit (So it looks like Var() Int, for example), you can edit the variable value in UEd
Oh, and does your special Sodacan class use 2 at once Cozmo? *Points to my last post*
