When Tusky vanishes, Aquaman and Aqualad ask for help in finding their walrus friend from all-knowing Oceanus, the Old Man of the Sea. Oceanus directs the Aqua-Duo to a volcanic region of ocean land, surrounded by illuminated water. Alas, it turns out that the two superheroes have fallen into a trap laid by their old nemesis The Fisherman--and before long, Aquaman is entrapped in a pile of rapidly hardening molten lava! It is up to Aqualad to rescue his companions with help from a few friendly whales. ~ Hal Erickson, Rovi
