The Avengers had gathered in the park for a friendly game of Frisbee when suddenly a creepy clown monster appeared out of nowhere and used some sort of strange magic to turn Tony Stark and Steve Rogers into keychains. The rest of the team was stunned and didn't know quite what to do.

Natasha Romanoff quickly sprang into action, analyzing the situation and trying to figure out where the monster had come from. Bruce Banner tried to reason with the monster, hoping to talk it down and convince it to release their friends. However, the clown seemed determined to keep Tony and Steve captive, cackling maniacally as it skipped around the park.

Finally, Hawkeye had had enough. He unslung his bow and arrow and took aim at the clown. Natasha nodded in approval, and they both fired at the monster, but their shots just bounced harmlessly off of its rubbery skin.

It was then that Thor stepped forward, brandishing his mighty hammer. With a shout of "FOR ASGARD!" the thunder god charged forward and landed a mighty blow on the clown's head. It let out a howl of pain and surprise, dropping both keychains to the ground.

The Avengers rushed forward to grab their friends and turn them back to normal. Bruce whispered calming words to the still-stunned Tony and Steve, while Natasha and Hawkeye kept an eye on the defeated clown monster.

In the end, the team emerged victorious, and they returned to their headquarters to regroup and debrief. Tony and Steve were still a bit shaken up from their ordeal, but they were grateful to their friends for rescuing them from the horrible fate of being keychains forever.
