Limited Telepathy. The pseudodragon can magically communicate simple ideas, emotions, and images telepathically with any creature within 100 feet of it that can understand a language.

Familiar. The pseudodragon can serve another creature as a familiar, forming a magic, telepathic bond with that willing companion.
