The Adventures of Rex the Wonder Dog #9

In WW2, in the Pacific, the island called the \"Dragon's Tooth\" is unbreachable because of a \"magic talisman\". Rex and Major Dennis raft ashore and see it, the Japanese Emperor's Sword of the Setting Sun that makes the troops invincible. Teaming up, Dennis attacks the troops while Rex steals the sword. Chased underwater, they're rescued by Navy artillery. A Marine notes, \"Somebody must've yanked this Dragon's Tooth!\"
