The ornamental design for snowman accessorykit, as shown and described.
FIG. 1 is a perspective view of the snowman accessory kit showing my new
design, the snowman shown in broken lines for illustrative purposes only;
FIG. 2 is a perspective view of a snowman, showing an example of how the
parts of the kit of FIG. 1 may be combined with a snow sculpture, the
latter being shown in phantom lines and forming no part of my design.
