I have an idea for a plush mouse. There could be many different types. Will be dyeable to your color choice. The basis would be a balance school with possibly balance blade sharpen blade and sandstorm. You could make hybrids of it such as frozen plush mouse or burnt plush mouse. I hope you all enjoy this idea.
Well making them school themed usually stops them from being dye-able. You may expect the frozen mouse to be blue, or the burnt mouse to have a blackened portion. Though if you just want the hybrid mice to only change what school the pet is, and not the appearance, then they could all have the same model and we could pick main color and trim color.
