All unusual things that I can see in the park / zoo are: 

- Two suns in the sky. We have only one sun in our solar system

- A tiger and a hippo are in the park. They are wild animals and especially can not be in the park.

- A girl is flying a bath instead of a kite. A bath is heavy so at least it can not hover in the air like that.

-------------------------------------

- A flying fish. Fish live underwater so they can easily die when they are on the sky.

- A monkey is walking outside. They should be in the cage.

- A parrot can hold something yellow. Birds have no fingers so it is impossible for them to hold thing by their wings.

- A girl is in the iron cage. She is not a wild animal.

- Dogs and puppies are in the cage. They are not wild animals, they should be adopted.

- A big candle instead of a fence pole and a snake instead of fence rope

- A big guild pencil instead of a guild pole.
