FROGS: If you ever actually pick up the frog tax, he will become your enemy. But if you dont tax them and instead help them defeat rats which can be found randomly as enemies or in rooms clashing with rats. If you help the frogs defeat the rats, they could lead you to their king. The king could give out wands which i have no idea howd they work but thas probably fine. The king gives quests to sabotage the rat king which eventually leads to his quest to assasinate the rat king. Granting you some prizes
Betrayl: you could betray both kings to get their crowns to command the rats/frogs but that could work as a dice. Random chance they believe you based on how may quests you did for them. If they believe you you could get the power to shoot rats/frogs out of a wand, power to get more speed if you betrayed the rat king, and higher jump if you betray the frog king. Probably more stuff than that but i am a little unsure what those are gonna be.
RATS :If you DO tax them however, the rat king could be interested. Not only giving you more quests to sabotage the frogs, but also giving you special wands and such (only obtained by the rats) the ideas for this wand i kinda forgot but i remember the ability to spawn a rat mount which i did make a suggestion for before. One of my new ideas is to turn yourself into a rat, basically a shrink spell but you are more mobile. Higher cooldown though. The quests for the rat are mostly the same but it leads to you assasinating the frog king which could allow you to get more prizes!!
