Each of the items in the list is the anagram of a character who is half of a famous duo. The bottom of the page contains anagrams of their partner. The complete list of partners is:
SHARK BOY (LAVA GIRL)
MICKEY (MINNIE)
LILO (STITCH)
BUZZ (WOODY)
HAN SOLO (CHEWBACCA)
BATMAN (ROBIN)
ROMEO (JULIET)
ANNA (ELSA)
DONALD (DAISY)
MARIO (LUIGI)
PHINEAS (FERB)
ERNIE (BERT)
At this point, everything has been used except for the numbers. If we index into the name of the second partner (taking the fourth letter of LAVA GIRL, the third letter of MINNIE, etc.), the phrase ANSWER IS DUET is formed. The answer is DUET.
