If You can not find  a pineapple mixadd well drained crushed pineapple to a yellow mix and instead of plain water use the drained juice as your liquid  adding  more juice from a can or water to make the 1 cup needed.  You might also add a teaspoon of pineapple extract if you want a deeper pineapple flavor.
