1: [Young]
When a young Spunge emerges from it's egg, it's filled with one thing: hot air! Over time, this squishy sapling begins to absorb moisture from it's environment: rainfall, swamp water, and even the humid air are a few of the young Spunge's favorite sources. The more H2O these monsters store in their inflatable chambers, the larger they get, until they grow into towering adults!
2: [Adult]
Adult Spunges are just as squeezable as they look, and truth to be told, they love a good hug! A piece of friendly advice: don't squeeze too hard when you're hugging this absorbent Monster goodbye, lest you end up drenched in years' worth of steamy Bog ooze.
3: [Prismatic]
This Spunge returned from the Prism Gate forever changed! What were once a huge gelatinous form and inflatable chambers have been altered at the molecular level to produce a quirky shrunken figure enclosed within a balloon-like casing - extraordinary!
