Though it makes sampling easy and fun, the Korg Volca Sample 2 is no toy. It offers 8MB (or up to 130 seconds) of memory, letting you add your own sounds easily via a micro USB port. (Don't have your own? It comes with 150 custom sounds.) From there, you can edit, morph, pitch, and sequence your samples, with a 16-step sequencer. When running on AA batteries, it can last 10 hours, so it's perfect for couch-jamming or roadtrips.
