One of the subjects the Professor masters in is Balloon Modelling. Below is a slideshow of some of the ballon models the Professor has mastered.
When balloon modeling is part of the a package the balloons the Professor creates are quick (for time reasons) dogs , swords , flowers etc. This ensures all party guests if they want one get a ballon
When booking the Professor purely for balloon modelling and he is there for many hours the balloons will be bigger and better and more impressive
The Professor also does special one off balloons which can be delivered and usually anything can be made. Examples can be seen in the slide show
