Can you be nude on poptropica?

No. The nudest you can get is wearing tight or short clothes. Or ones that show your belly.

Technically you can. On Mythology Island you can customize the Minotaur's fur and it will be the color of your poptropican's skin.

Poptropica Towers is the area in the far left of the island.

It was a name thought up by Jeff Kinney and the creators of the concept, with the vague connotation of a "tropical" island setting.
