These skeletal creatures were found in the Halloween section of Walmart. They are $4.98 each.
They have screw holes all along one side, like Chap Mei and other lower value toylines so I photographed their good sides
The Gryffin and Velociraptor feature swivel heads and hinged jaws. The Triceratops only has the hinged jaw (this is the least impressive of the 3 due to not having any form of visible neck, looks like a turtle pulling its head in
). All 3 feature bendy tails (rubber with a wire running through it).
They are decently sized as seen in the images below with a 4" "Fortnite" figure to show their scale.
