According to some new listings from a South African retailer, Nintendo has plans to release several new, announced amiibo. Among those listed are Greninja and Jigglypuff, two Pokemon which are fighters in Smash Bros. It was already assumed by most that these two amiibo would be released. The more surprising listings suggest that Nintendo may also be releasing a Splatoon line of amiibo. These listings appear to include an amiibo for the male and female characters in Splatoon, as well as a squid amiibo.
Currently, Nintendo has not announced any official plans for Splatoon amiibo. The game itself is slotted to release this May.
