Huh?? What the....??

Came in to the office yesterday morning to find this "fiesta" happening on my table.
Can't really make out what's happening? Here's a better view:

Batman doing Batman... in public....with all the other figurines (and stuffed toys) from different 'worlds' watching... ewe.... get a room man!

Wow! We do have a lot of toys. Half of them are mine and half of them are W's. And you've guessed it right. The choreographer - W.

Oh! Can you name all the characters? :p
