Well... you can play games to earn Tu (the Res currency) and you can either buy or collect eggs by exploring the different planets. If you hatch a natural pet, don't bother keeping it because they're worth virtually nothing :x Your hatchery is found on the top left corner, the orange egg. You need to incubate eggs fully before you can hatch them. You can view all the pets and their colours, rarity, what planet they're found on, how long they need to be incubated for etc. on the top right corner under "Information". Um... going on the forums is a good way to meet new people c:
I hope you enjoy Res. It's pretty awesome c8 If you need any help with anything feel free to Rmail me ;)
Yes that siggy is adorable ;;o;;
