Can you catch the Eel? It's slippery!
Download the puzzle here: <Letter Size> <A4>. Print it on card stock, double-sided in color or grayscale. If you cannot print double-sided, print only the first page. If you have no card stock, paper will do.
Then cut out the four pieces and arrange them without overlapping to make a symmetric shape. You may flip the pieces over.
Good luck!
