    Let's say the toffees are A, B, and C.

    The egg must have at least one toffee of each sort, so each egg looks like

    A B C X X X

    where X is one of A, B, or C.

    There are 3 choices for each X, and 3 X's, so that's 3*3*3 ways to do it.  There's your answer.

    Sorry, I started eating the eggs before I finished counting them. It lost track after 8, so it's at least that many.
