I like the idea of a tadpole-romance bait-and-switch though. Suppose you reject the tadpole-dream-lovers advances and then romance a companion. The tadpole should take note of your romance and try to adopt the companion's appearance instead to trick you in a dream. Like...
"I'm so glad I found you. What is this dream place?" the Companion-Tadpole says.
"Let's get out of here before it comes back. Let me in."
