Scorpion stood on the muddy bank, his pincers twitching anxiously as he looked across the river. The water was high, and he needed to cross to the other side. His eyes caught sight of Mr. Frog, who was lounging nearby, his green skin glistening in the sun. "Hello, Mr. Frog," he called out, trying to sound friendly. "Could you help me cross the river? I can't swim, and I need to get to the other side." Mr. Frog eyed Scorpion warily, knowing full well of his reputation. "Why should I trust you? How do I know you won't sting me?"

Scorpion shifted uncomfortably, trying to suppress his natural instincts. "If I sting you while we're crossing, we'll both drown," he reasoned. "I promise, I won't sting you. I just need your help." Mr. Frog thought for a moment, his eyes narrowing. He knew the risk, but the logic seemed sound. "Alright, climb on my back," he finally agreed, albeit reluctantly.

The journey began smoothly, with Mr. Frog expertly navigating the currents. Scorpion held on tightly, his eyes fixed on the far bank. The river was wide, and the current was stronger than he'd anticipated. "You're doing great, Mr. Frog," Scorpion remarked, trying to keep the conversation light. But beneath his calm facade, he felt a familiar itch in his tail.

Scorpion couldn't help himself. The urge was too strong, and against his better judgment, he stung Mr. Frog. "Why?!" cried Mr. Frog, a pained look crossing his face as the venom began to take effect. "Now we'll both perish!" Scorpion felt a pang of regret but said simply, "It's in my nature."

The poison worked quickly, and Mr. Frog's movements slowed, his strength failing. The river, relentless and uncaring, pulled them both under.

As the waters calmed, the tale of Scorpion and Mr. Frog became a somber reminder of the dangers of misplaced trust and the consequences of one's true nature.
