I loved the concept of Pal Mickey, but there were a few downsides. First off, he was kind of heavy and in the parks, you could barely hear him. You had to wear him on a lanyard or carry him and 90+ degree heat he became cumbersome really fast!
Pal Mickey would have been a great idea if he was some type of larger (think 3 1/2 inches) clip-on pin that could you attach to the handle of a tote bag, a lanyard, backpack, belt loop etc. He could come in several different versions, Steamboat, Sorceror, Mickey in his tux, etc.
I didn't mind the buzzing to let me know something was going on, but wouldn't it have been cool (and less annoying), if maybe a brief Mickey Mouse Club chime played instead or another classically Disney tune. He could have had several buttons on him like Play or Ignore. If they can make a Nintendo DS Lite as small as it is, they certainly can have used better technology for Pal Mickey. In keeping with a Nintendo DS Lite, they could even have had additional game/trivia chips to go along with the Pal. Sort of like the old razor and razor blade concept!
