One girl's epic adventure to open a door.
For those new to text adventures, interactive fiction, or in this case, interactive fan fiction, try things like this: go north (or just n), inventory (or just i) look, look at Elsa (or examine Elsa, or ex Elsa), wait, talk to Elsa, ask Elsa about ice. Try verbs like open, paint, climb, bounce, take, drop, give, buy, jump, use, pour. Don't be too complex, shorter is better. Also there are more verbs than are listed in the drop down menus.
