Ninja Slime

Ninja Slime is the kind of novelty slime people buy as a sensory toy or a little desk distraction, usually because it can be stretched, squished, and folded over and over. By our assessment, its best trait is immediate tactile play: slime gives fast, messy, hands-on entertainment without much setup. The downside is equally plain, since slime is easy to get on fabric, can dry out, and needs a bit of supervision if children are using it. In practice it is more about the feel than about any deeper game, so it works in short bursts and then goes back into a container. It sits in the crowded middle of fidget toys and putty-like playthings, and the name suggests the usual playful, not serious, version of that category.
