Subject: enemies
Four times I have been here,
this not being my native land.
Thrice real, once dream,
once an item, twice a foe.
Apparently they were in 4 games.
Posted so people dont have to go back a page.
So, they've been in four games. One was Link's Awakening because it was a dream, meaning they were also probably in the two Oracle games, since all enemies in that game were copy'n'pasted. Meaning they were likely Mario-based enemies. Further exemplified by the fact that this is not their native land. Once an item narrows it down to only one enemy, which was a bit of a pet in Link's Awakening. however, this enemy wasn't in the Oracles, but in 4 Swords and 4 Swords Adventures.
The Answer is: Chain Chomp/Bow Wow.
