i don't know how to use playmodb.
Playmodb.org is the website.
Just click on the picture and it will take you to a form.
Basically of you read the form it is pretty obvious how to use it.
To find for instance this klicky you go to the "Who's that Klicky?" section (third section)
Then click the "Find Klickies with any characteristics you specify!" link
This will take you to a new form.
Now I chose the options "Leg Colour: White" and "Footwear Colour: Red" and the fourth picture should be the Handsome Prince.
Hope this helps!
