How Do I Get Rare Costumes On Poptropica?

In the green building in early poptropica . There is a hypnotic outfit inside one of the flowers... I mean in poptropica towers in early poptropica.

You have to go to a good place ( I pick arcade and go in and out and look around) (if you have a cool costume go fast) and look around most of the time its at the pop shop, on poptropica regular island, or any new island.   

P:S. I'm looking for the black cat outfit (if you can help message me) (my username is yellow lightning)

You have to jump up and down 3 times on the top of a roof in Spy Island

No

You get glider from da vinci in time tangled island
go to top of cave in viking world then glide right as far as you can

I ROCK!
