Mermaid Escape

It is a hot summer day and so you have decided to go to the beach which is probably the best place to cool off. There you start finding so many different types of sea creatures that have come to the shore. It feels exciting because you have never seen them in real prior to this. However, you get shocked to see a mermaid. How you wished that you could interact with the mermaid and get to know more about her. Unfortunately she is locked inside a cage. Rescuing her will be a noble thing to do but for that you must have excellent puzzle solving skills.
