Animation in response to a user response?

Hi,

I'm fairly new to UNITY and have a question about animations. I want to design a 2D trivia game where if a user answers incorrectly, an animation will play as a result. For example, for every wrong answer a user makes, a piece of a photo will appear (like a puzzle) until the photo is complete. Then the game is over. You can think of it like hangman where a user can keep guessing until the hangman is completely drawn.

I do not know how to design such a thing in UNITY and I am having a hard time Googling results. Does anyone know of any good resources I can check out, or have explanations on how I can go about doing such a thing?

Thank you!
