Balloon

A Balloon (バルーン) is an inorganic type of monster. Balloons are shown throughout Melromarc to be one of the weakest monsters and are said to spawn from Balloon Legions.

Overview
They are commonly found in the fields around Melromarc and come in a variety of different colors consisting of orange, yellow and red. Orange is the most commonly known monsters they are usually referred to as Orange Balloons.

When killed, they drop balloon skins which are commonly sold and bought at Castle Town in Melromarc. Their skin is used to make toy balls to be later sold again.

Despite having an overall weak defense, which makes them easily killable, they do pack a strong bite.

Depending on the color of the balloon, their overall strength is increased, Orange Balloons being the weakest to Red Balloons being the strongest. Despite their strength difference, each species still grant only 1 EXP.

History
In the past there was a variant of the balloon monster called a "Snake Balloon" which was available in various colors. They used to reside in Siltvelt and demi-human areas but were hunting to extinction. They could be used as pool inner tubes or balloon art which was quite popular in the past.

Holn Anthreya, a genius alchemist at the time had the ambitious goal of making balloons into the ultimate monster.
