Thanks for replying At first I thought I would get stuck there forever but luckily after going through my back pack I found an escape rope and that helped me escape. Ever since i always stock myself with escape ropes. Right now I'm in hoen.
The sailor NPC took me to munchlax island without me being a champion(I've only received 2 badges) I'm currently stuck in munchlax resort and am unable to leave. I get stuck at the stairs every time I approach it.
