Episode 3 Monkey Island is bugged - Tongue of the Manatee

DoflamingoGT

I bought the game on Steam but i found out that episode 3 is bugged, when you enter the giant manatee to pick up the Tongue of the Manatee to learn the language it's not there for me, on youtube i saw that there is but for me the yellow bile is empty without the item, i did everything previous thing and now im stuck like this

EDIT: It's ok now i fixed it some people from Steam gave me their save files to download and they had the item
