Ninja various vehicles builds

Got these few medium box Ninja sets from SY. Some of the design builds look like cars or bike, but some look like a bug with spider fangs, and another according to my son, looks like a chicken ( or a mantis to me). These can be combined with another design builds from another box to make a bigger – Weirder looking design. Are these design from Lego or from SY? As usual, SY fitting quality is mediocre, but surprisingly, this sets stud gun can work, shoots well too,,, but SY did not provide extra bullets when their guns are able to function..

^6 legged Spider attack vehicle (this comes with 2 minifigs)

Mantis machine

Nice looking armor plated bike (front blue blasters are VERY loose)
