Yeah ... the hamster in the microwave in 3D :-)
It's really good to hear that there will be a speech version of MM3D ... I can't wait to hear Nurse Edna speaking.
Have you seen the new youtube video:

Unfortunately they only show the outside area, but if you take a closer look you'll find a lot of differences to the alpha version, e.g. a car (Dave's car???) and the mansion has a lot of changes (ivy has been added all around it and there're some broken wood trusses at the porch). I really love those changes ... looks great. Would be great to see more of the game.
