you have to press fly then go any where in Naboti island or press float
use the lobster that you can get after completing cap'n salty's quest
You get rid of it by using the lobster to clamp onto the light in the lighthouse and turning it in the direction of the school.
You get the Egyptian blue lily from the blue nile falls Then you go back to the town Nabooti and trade the flower for a desert turban from the lady at the market stalls.
on counterfeit island in the museum when there are lasers you cant turn them off. you hide behind the statue's
To get the seagull away, you have to turn the lighthouse light. Use the lobster.
you have to go to a random poptropica person and customize and you just take it off.
The bell on Big Nate Island on poptropica is located on the top school building. To reach it when you have the clapper, you need to get rid of the seagull there. (see related question)
get rid of the teens
You can't
maybe
You can't get rid of an item.
If you are on Super Hero Island, you can't get rid of your would-be sidekick Ned Noodlehead. If you have dialed "1337" on the Nabooti Island cellphone, then you now look like a nerd (like Ned). There is no simple way to remove the costuming changes created by the phone. You will just have to "copy" hair, teeth, and costume from other Poptropica people. I heartily suggest that you spend the 250 credits for the "costume saver" in the store. You can save up to three appearances at a time, and change them anytime you want by choosing, altering, and saving again. This way you can try out all of the costumes (and cell phone codes : 411, 911, 1225, and 1337) without having to get rid of them piecemeal.
