Can you have fun here with just the admission price and not buying extras? Do you have to buy the tokens to touch the animals? Do you still get to go in with the birds if you don't buy the food? etc...

Try feeding the birds. There is no cost to that and its a great experience. Warning, can get messy.

Yes you can still have fun without buying the tokens for food. It is just a better experience with the food. The animals still come ro

it is a lot more fun with tokens.

The birds, otters and the sloth you need tokens to play with them but when i went there i didnt buy tokens and still had fun

Yes you can. Tokens pay for food to feed the animals.

No need to buy any of the extras. You can still go in with the birds or touch the animals even if you don't buy food.

You have to buy tokens in order to interact with the animals.
