Unique Wishlsit

So I help work on a site called EggCavity.com

This site is a ‘fan site’ for a game called EggCave.

The owner of the site uses ‘Profile Builder’ to manage profile information (if this matters).

On this game site there are creatures to collect. I am hoping to make a feature for users where they can create a wishlist that they can share a link to on their EggCave.com profile.

EggCavity isn’t a shop site so there is nothing to purchase, so none of the plugins I found would work.

To add creatures to the wishlist I would like to display an image of each creature with a check box below the image so they can add multiple creatures at a time. Once they’ve selected all the creatures they want to add, I am hoping they can then select either at the bottom of the page or on the next page how many of each they want. Then it would move to another page where they can customize the list (add a gender, the age of the creature, a notes box, if the creature is frozen or not, etc.), reorder the list, add more creatures (send back to add page), delete creatures, etc.

If someone could just give me a push in the right direction for where to even being to do any of these things I would greatly appreciate it.

If you know of any plugins that would help me achieve this, that would also be very helpful.
