Exploding Frogs?

Exploding toads
BERLIN (AP) -- More than 1,000 toads have puffed up and exploded in a Hamburg pond in recent weeks, and German scientists have no explanation for what's causing it. Both the pond water and body parts of the toads have been tested, but scientists have been unable to find a bacteria or virus that would cause the toads to swell up and pop. The toads at a pond in the upscale neighbourhood of Altona have been blowing up since the beginning of the month, filling up like balloons until their stomachs suddenly burst.
