Field Sponge

Common pest monsters that harass farmers, by being a threat to their vegetable crops. Field Sponges are sometimes kept as pets, although it is rare to observe any affectionate behavior in a Sponge.

Worst they can do is cause minor scratches.

When resting, Field Sponges retreat to underground burrows.
