However, if you're interested in the variety of Mickey ears that were present in VMK, you might try:
* Searching for old VMK wikis or fan sites: These might have lists or images of the different Mickey ears.
* Joining online communities dedicated to VMK: Members may have preserved information about the game's various items, including the Mickey ears.
Unfortunately, without access to the game itself, it's difficult to give a precise number of Mickey ear types.
