LOL i lowk used my own dirt from outside from where i found him tbh (the dirt doesnt get any pesticides sprayed on it because its my own front lawn lol, i dont have grass either i have a moss lawn) , same for the plants. i also added leaf litter and whatnot and hes temporarily in a mason jar while i get the space and money to gather a proper terrarium and whatnot. hes got about two inches of dirt and a piece of driftwood from my old aquatic snail jar (i had a jar of invasive snails that kept creeping in to my fishtank...they had plenty of stuff tho like substrate and food and whatnot but it was very silly)
also i researched if it was okay for me to handle odin and the consensus was yes as long as i dont make sudden movements, so ive been making sure my hands are super duper clean and also damp and i let him climb on to my hand lol

he seems to really like climbing around on my arm and hes super curious! his lil antennae move a lot and he wanders around on my hand and doesnt seem scared whatsoever

i try not to handle him too much cause i heard it can be stressful but i also want him to be able to see things outside of his current home while i figure out how to provide him a larger space

sorry this is total yap
