Gold Koopeleon

The Gold Koopeleon (Japanese: ノコレオンゴールド Gold Nokoreon) is a rare variety of Koopeleon, the Koopa chameleon. In Mario & Luigi: Partners in Time, Gold Koopeleons live in the Thwomp Caverns, the interior of the Thwomp Volcano. Gold Koopeleons, as their name implies, resemble regular Koopeleons, except they are gold and flashing.

As the Koopeleon, Gold Koopeleons have the ability to turn invisible. Unlike Koopaleons, however Gold Koopeleons turn invisible to hide from attackers. Gold Koopeleons give many Gold Coins and plenty of EXP. Additionally, although Gold Koopeleons have high defense, they also have low HP.

Gold Koopeleons tend to flee rather than fight. However, if a Gold Koopeleon decides to fight, it may use two attacks in battle. First, the Gold Koopeleon may turn invisible and attempt to run into the attacker. This attack can be countered by jumping. Secondly, a Gold Koopeleon may run up to Mario or Luigi and hit him with its tongue. Again, this attack can be dodged by jumping. Sometimes, the Gold Koopeleon performs multiple tongue strikes, meaning the Mario Bros. have to jump multiple times to avoid taking damage.

Trivia
Gold Koopeleons, Gold Beanies, Shiny Goombas and Amazy Dayzees are the only enemies to appear in a Mario RPG game with a lot of coins.
