After seeing some gameplay from LBP2, it looks like Sackbots just get electrocuted when they touch water.
That's a little bit wierd seeing as they're supposed to mimic the actions of a Sackboy.
Also they can only be equipped with the Grabinator and Creatinator...
I don't know why they wouldn't be able to use a grappling hook if they were being controlled via Controllinator.
Maybe it will be fixed in a later build of the game.
