That would be so cool!!! Its not even a problem that Horton is nice as he is also an idiot so you can explain that as him being that vast a being and humans as being just as incompressible to him as he is to us.

Just an idea :P " The doomsday cult of Whoville is a strange one as unlike many elder god cults they are trying to save the world, not that outsiders know that. It is said it all started with the mayor who thought he heard a voice in the thunder and built a device to listen to it. With this he made the discovery of Horton a immense beast bigger than the mayors universe with two large tusks extending from its toothy maw framing a fleshy tendril extending toward the world. It’s voice was thunder and it’s breath tempest but what the mayor noticed most was Horton’s large ears and kind, beady may they be, eyes. The beast was the one charged with guarding this world from the dangers of his alien forest as the world was transported to a new resting place. The mayor, and soon the town, agreed to be his hands on earth safe guarding it from horrors attempting to extort it. Alas *Horton * being what he was left marks on the town and its inhabitants. The town has a perpetual storm above it and the people have grown large and impossibly muscled with devices strapped to their skulls resembling large ears to hear their gods will. This is why though they do good in the world they are as feared as the monsters they fight" If that isn’t horror enough add descriptions of the horrors (insects) that the cult fight and the earth shaking battles Horton has with other dark gods( other animals). Also pretend they don’t know what an elephant is.
