Given that Lance (@gilove2dance) and Keith (@incaseyouart) jumped into an alien ship in their show Voltron: Legendary Defender (on Netflix now!), I think they would probably love to travel with the Doctor…especially since he can bring them home at any time.
But what is Winnie the Pooh doing there? (Dragon didn’t want to leave her favourite person: Keith)
Audrey Ramirez and Helga Sinclair stopped by during their search for Atlantis in OCC 2017. Considering I saw a Milo and Kida at OCC 2018 (I sadly did not get a picture), I think they may have succeeded!
