He is a pirate captain who menaces Fort Ridley and the islands of Skullduggery island. You must defeat him there in order to recover the hidden treasure.
He also appears (as constantly sleeping clones) on Super Villain island. You beat his dream by not waking any of them up as you gather items, and eventually steal his Ship in a Bottle totem.

It isn't possible. The whole point of getting a big ship on Skullduggery Island is so that you can fight an even battle against Captain Crawfish. There are no magic shortcuts that work on Poptropica.
first you get money and upgrade your ship for 1000000 to the warship then you go and find the map after that you go and defeat captain crawfish
there is a good chance that the 22nd poptropica island will be calles robots island due to the robots in the daily pop, the wallpaper that captain crawfish put on the creators blog, and the legend is coming trailer.
Find the 5 pieces of the map and examine it and you'll see where skullduggery is. Dock there then get out of there and you'll find captain crawfish

Scurvy Sam isn't a person you need to find on Poptropica. It is just a name said by the female pirate (one of Captain Crawfish's crew) inside Petey's Pub.
Assuming that "babies" would be the subject of the game (rather than those who play it), there would not seem to be any similar game. Poptropica is an adventure game, and would probably not have challenges such as "how do you diaper Captain Crawfish?"
There are many of them. Everyone from captain crawfish to binary bard are actually creators. If you've friended a creator, you will know because the name will actualy say "Black Widow" or "Shark Boy.
