slinky!!

them :0

The green and pink arm is one of those weaved fidget toys with the marble inside !! 

The rainbow arm is like hard plastic building blocks

The mushroom like leg is like a foam squishy

The segmented leg is like an action figures arm

And finally, the tail is like one of those fidget slugs that slide around like these things !!

Whole guy is made of the same type of plastic unless specified otherwise
