We all know by now that the Dr. Mario amiibo will be exclusive to Target after release on 9/11/2015.
amiibo website. Underneath the amiibo's description you can read "Exclusively at Target at launch". However, we have a new rumor in circulation around the internet now about the rarer amiibo figures may be in reproduction, including the Gold Super Mario amiibo figure. Nintendo's CPSIA is for their product safety but apparently also lists what products are getting restocked and I guess that some of the rarer amiibo are on that list. This should make the ones who couldn't snag up rare amiibo figures when they were released a bit happier.
Game on and Keep it Rehl!
