NeeDoh The Groovy Glob
If you buy one fidget under five dollars, make it this. The NeeDoh is a dough-filled ball that squishes flat, oozes back into shape, and takes endless squeezing without tearing — the rare cheap fidget that survives a backpack and a year of math class. It's the one we'd hand a kid who clicks pens and bounces knees: quiet, pocket-sized, and genuinely calming to work in one hand. Sold loose by color, so it's easy to grab a few for the price of one fancier toy.
