Hi RabidRainbows. Welcome to res!
I'd recommend reading the FAQ's and site rules if you haven't already, these are located on the left hand side under the logout button.
There's a lot of fun things to do on here such as playing games like precious pearl quandary, mystery box and Twantie Cay, these will aid you in earning tu. If you go to the apple tree with each of your pets you can get a free apples. These games are all in the 'luck' section. Once you have a bit of tu, investing it in stocks is a great way to make loads of tu if you're patient. Stocks can seem a bit confusing at first but if you'd like a stock guide I can send you one!
A few dailies you can do are The Enchanted springs and the forest where you can pick a flower and explore for abandoned pets, these are both on Atquati. There is a trash isthmus on Relcore where you can take a free item every day.
I hope this helped and if you have any more questions feel free to ask. So many of us on here are more than willing to help you settle in :D
