Fear Tech's Sludge Balloon is a tool in Disney Infinity. It is obtained by collecting all 20 Fear Tech pennants in the Monsters University Playset. When thrown at an enemy or other player, it will coat them in an transparent, orange slime. It is also the default tool of Fear Tech Student Patrol 1, 2, and 3.
For some unknown reason, the balloon does not reappear in Disney Infinity 2.0, although the Fear Tech Students still throw them..
