In the colors of orange, yellow, red, purple, and green, the mascot takes shape from Nanjing’s colorful and special river stone product, or “rain-flower pebble” as many Chinese call them, and is outfitted with a full set of professional roller skating equipment.

It incorporates aspects of the host city’s majestic local stone – its brightness and vibrancy – and sets the tone for fun, colorful, and energetic roller games.
