Purchased on LetGo. All 14 critters are present and 5 orbs. Bottle is glass, not plastic. The pump is a little noisy but not much different from a normal fish tank air pump. I so wish they included more jelly fish as they are the best by far. The amount of critters that are moving around vary from minute to minute. Sometimes a critter has to fall to knock others towards the bubbles. They should still make this if you ask me it would sell well.
