This was a art 1 project last year and I chose to use foxes. I used 3 in it and their tails are also a letter too see. The 'A' fox's tail is the 's' the 'h' fox's tails is the 'L' and that one fox and its tail is the 'y' ^w^ This I can do for others but be aware that its gonna be hard to make and 'x','w', 'm', 'e', and other letters lol so other animals will be used to fix the problem if neccesary. If you dun want to have a whole bunch of foxes and then a octopus to be another letter then I suggest you think about it first XD
