There are now 45 shamrocks, 36 Trojan heads and 5 combined medallions on the shillelaghs. They also tend to favour stereotypical parts of Irish culture&colon; shamrocks, Leprechauns and shillelaghs. The success of the phrase led the San Diego Padres store to carry inflatable shillelaghs. The second shillelaghs is slightly longer and contains medallions from the 1990 game onwards. Shillelaghs are sometimes referred to in a similar context in folk songs. Shillelaghs are traditionally made from blackthorn (sloe) wood ("Prunus spinosa") or oak.
