She will also spawn an exit portal with a Dragon egg on top. Entering the portal will activate a text cutscene that lasts for an average of 8 minutes, 30 seconds. After the cutscene, the player will be teleported to their spawn point/Bed in The Overworld.
Unfortunately there is no general answer because pound is a measurement of weight and cup is a measurement of volume. It depends on what you're measuring. For example: For water 1 cup = 8 fluid ounces = 8 ounces weight = 0.5 pounds. So 2 cups water weighs 1 pound. But this only works for water.
How many pounds are in one cup? It depends on the size on the cup you are talking about and the weight of things in the cup but a cup is not a true measurement like ounces to pounds.
