Spotted some new(?) Wicked Cool Toys Pikachu plush at Walmart for the Halloween season. Theres a Pikachu with a Pumpkin hat on, one with a Witch hat and another holding a trick or treat pumpkin.
They're pretty cute little guys, pretty sure they retail for $14.98 but a quick search shows they may be cheaper at other retailers like Hot Topic.
I didnt grab a pic of the other assortment but I spotted a Marshadow plush and some other assorted ghost mons too, although that may just be an older assortment/what they had left.
