Write a story about a Goblin who goes on a long, protracted journey. He spends long stretches in the midst of others, to the detriment of his privacy. He needs to shit very badly and holds it for days. Eventually, it becomes too much to bear, and he's forced to drop his pants and shit where he stands. He shits a gargantuan amount and feels much, much better afterwards, despite the embarrassment and ridicule. include dialogue and conversation
