In Mystery Of Wistimere, the four horses carried the Vermin to Wistimere, protected by Lola, Auberon, Valori, and Vesper in a deadly Troll encounter. Their carriage would prove useful in shielding Luana Yinshera from the prying eyes of the public and Mayor Perceval LaPall as the adventurers solved the mystery plaguing the town.
A Riding Horse native to Oldoan, Biscuit was raised in stables belonging to Vermhaxaandes Sharhydrox. Reliable, swift, and well-mannered, he was considered by Hydrox to be one of the few horses of his retinue reliable enough for Adventurers.
Biscuit eventually became an animal companion of the Vermin alongside cousins Ginger, Fudgeeo, and Oreo, and he became the usual steed of Lola Windwisper.
