Peppa and her friends Suzy and Emily are making $3$ masks: a knight mask, a pirate mask and an elf mask. The one wearing the knight mask must always tell the truth, the one wearing the pirate mask must always lie and the one wearing the elf mask could sometimes lie and sometimes tell the truth. After making three masks, one of each kind, they all wear one each and make the following statements:

$\text{Peppa : I am wearing an elf mask.}$

   $\text{Suzy :  That is true.}$

 $\text{Emily : I am not wearing an elf mask.}$

What kind of mask is each one wearing?
