Silk: Prom Improvements

Promotional tile for Silk. If included by agreement, it replaces one of the original improvement tiles, as games use a maximum of four improvement tiles. The first player to place three silkworms of their color on each of three pastures of the same type, for a total of nine silkworms on equally valued tiles, immediately scores 5 silk points. The silkworm improvement marker is then flipped over.
