Endlessly asking questions, the Quibble hatchling is filled to the brim with wonder. Monsters put considerable effort into scavenging resonant rocks for the developing Quibble, as a colorful keyboard is the only thing that will distract it from its constant queries.
A Quibble is considered fully developed when it ceases to interrogate everyone within earshot. Founts of information, usually conflicting, the heads bicker continuously. Anyone looking for a second opinion need only make one stop with a Quibble around!
The Quibble is a turquoise two-headed swan with a blue tailfan. It sits in a circular pond with a keyboard of rainbow-colored "white keys". Its two heads have slightly differing crests but otherwise are both the same, one with a green crest and one with a purple crest. It also has a pair of small wings, each wing being colored to the color of the side at the same side as the associated head.[Clarify]
As an adult, its feathers become blue, has longer necks and beaks, longer crests, and a longer tailfan. Other features similar to the Quibble from the original game appear with in the adult Quibble, apart from the graphical enhancements added to it. The rainbow-colored keyboard is replaced by a rather stony keyboard arranged in a proper key formation, although the number of keys present only range in a single octave.
Like in the original game, the Quibble's contribution to an island's song is the sound of a piano. Each head is responsible for playing the notes on its own side of the instrument. The head with the purple crest plays the lower notes, while the head with the green crest plays the higher notes.
On the Continent, the Quibble's piano sounds much older, similarly to a tack piano.
The Quibble can be bred with a combination of Air and Water.
The Quibble will request food and/or non-food items that are the products of Structures. If you cannot give the monster the food or items it requires, you can click the New Order button. After a 15 minute wait, it will ask for a new combination of foods or other items.
When given the wanted foods or items, like any monster, it will reward you coins.
Quibble can be teleported to Cave Island at level 20 for a reward of 5 diamonds Teleport time for Quibble is 10 hours and Party Island at level 5 for a reward of 2 diamonds Teleport time for Quibble is 5 minutes.
The verb "to quibble" means to argue insistently about an irrelevant subject, much like the namesake monster is said to do.
The baby Quibble's rainbow keyboard is a reference to the description of the Rare Quibble, which states that Quibble hatchlings use colorful keyboards, rather than the standard black and white keyboard that the adult Quibbles use.
The baby Quibble's instrument does not have black keys, unlike the Rare Quibble's.
