Wild wicked witch

I’m a wild wicked witch
That’s right, you heard me bitch  
You can poke at me with your sticks
But I’ll never miss a trick
 
Let me cast a spell
Ensnare you in my hell  
You can fight, you can yell  
But the magic will always tell
 
Tell me where you’re hiding
Where you’ve ran, which wall you’re climbing  
It’s all just a case of timing  
I’m forever learning, forever finding
 
Finding things I’d left behind
Finding things I’d hidden  
Finding things I’d cast aside
To things I’d said good riddance
 
And yet as I stir my pot, it bubbles and boils
Billowing smoke with fluorescent gargoyles  
All rising to the surface, all swimming about  
From where do they escape, from where do they hence sprout
