Return of the Creature Decoy

So far I am finding it difficult to get past the Collector Leviathan, both ways. We need the Creature Decoy to distract it. Even if this seems pointless with its intelligence, you could counteract this by have different types that make different sounds or lights with different materials for crafting, since a standard Decoy would likely only work on a Collector once, and then it would have figured out it is a distraction.
