So you like Jefferson Airplane. Now tell me which pill did you take? The one that makes you larger or the one that makes you smaller? I think it was the one that makes you smaller and that you're still taking them and tripping into the fantastical worlds you create.
I had to think about that one foe a moment. I think I would go for the smaller. Of course some costumes to fit into the scenery would be necessary...it conjures up all sorts of fantastic adventuring images.
I like the idea of Vampire shrooms and perhaps you should add a goblin smoking a hookah 
NOW THAT'S AN IDEA! I have a couple of hookahs, in miniature that is, I made for part of a commission project.
AND I could make a really big mushroom for him to sit on...maybe someone to keep him company. This could be a cool display piece.
Here's an example of using larger Mushroom as scenic props:

My Night Goblins were all standing on, hiding behind, leaning against, or, in this case, bounding over Big Mushrooms. That's a closeup of Barf O'Bilge's Bounding Boys.
