Good point! Come to think of it, why Ro-Bear Bill and Belle? I mean if the people of Third Earth came under any sort of attack, would the Berbils really be able to fight for them or protect them? Highly doubtful considering their gentle, non-violent nature and crude weaponry. But I guess the thing is that there aren't really many "warrior-ish" Third Earth natives to begin with. Apart from Snowman, the Warrior Maidens, and the Tuskas, most of the other natives (Wollos, Bolkins, Molemen, Brutemen etc.) are always the ones requiring protection and incapable of offering it to others. Perhaps Mumm-Rana and Sondora might be a good choice to be the Guardians as well since they possess some magical powers.
