all the chibi guardians. They will follow you around in this form and transform when in battle into their full form :P
Which explains their two forms. Besides, it makes you lag anyways with so many huge stuff running around. So keep it chibi XD
Oh and for the extra, still laughing pretty hard from kGM's official comic.
Basically after the card identification, bunny got her cute little guardian, while sheep got a... eh very chilly and creepy one @_@
