1: [Young]
A Quarrister tyke is essentially six toddlers bundled together, so the fact it doesn't have legs is a very good thing: gets into less trouble that way! Being a starry-eyed youngster, it is prone to daydreaming, making it easy to sneak up on and startle. Fortunately, its weight distribution is such that it cannot fall over - be it surprise, ferocious winds, or when subjected to the blast from a Sooza's horn. It excels at string art, water aerobics, and zorbing.
2: [Adult]
Despite zero privacy and the cacophony of six voices in its heads at all times, the Quarrister remains jovial and unflappable amidst the chaos, while remaining single-minded in its devotion for its shared purpose: to form a retaining wall of sound that bolsters the greater monster chorus. Burly though it may be, the Quarrister excels at rhythm gymnastics and unicycling - but it can't scratch its own back.
3: [Prismatic]
This Quarrister returned from the Prism Gate forever changed! While its bulky body was previously made up of several rock faces fused together, it has been altered at the molecular level to become a shining suit of armor, complete with diverse heraldic adornments and vocalizing ailettes - extraordinary!
