It's an ideal show for kids, but it never leaves the adults behind - indeed, it's hard not to feel swept along in the fast-moving slapstick antics of the foursome. Exploring a toybox left on stage, they find all kinds of miraculously inventive tricks to play with its contents, from a paint roller that becomes a helicopter to magically colour-changing juggling rings.
Relationships between the performers are a joy to behold and their facial expressions - especially those of rotund, bowl-headed Jun Woo - are hilarious. The laughs come thick and fast in a relentless barrage. There's also some warm-hearted audience participation and clever use of live sound effects.
It might not be the most sophisticated show on the Fringe, but I doubt you'll experience an hour of more unbridled fun.
