TF: Fold the base up to the sides. Inside are six legs - unfold them. One set of three legs slides up to match the others. Rotate the legs at the knees. Split the lense mount in two , fold down to the sides, fold out the eyes and fold out the arms from under the lense mount. Fold the tops of the lense mounts underneath and bring them together. Fold the stem of the Microscope under the base and rotate the lense mount. Extend the legs.
No, that's not the best transformation description I've ever written. But all the legs fell off while I was doing it and it's hard to know what you're doing with a non-humanoid robotmode. What you get is some sort of six legged insect with huge eyes, antennae and tiny arms. Ball joints at each knee and hip as well as the shoulders while the arms bend.
VERY fragile - as I mentioned the legs fell off and several of the thin grey ball sockets have cracks in. AVOID. I'm now going to try to rebuild mine in the more stable microscope mode.
