Bunyip

My version of the mythological Bunyip, which I have heard was used by aboriginal people to prevent their young children from going near waterholes, particularly at night.
"Don't go there! The Bunyip will get ya!" 
 (Other nasties used this way were Mook Mooks -
"Don't go there! The Mook Mooks will get ya!")  
Will write a short story about this particular Bunyip, who I tried not to make TOO scary??
