Miguel the Bed Troll...

Today River and I were laying in bed watching TV when I saw him take my phone and hide it. He then said "hey, where's your phone?". I replied "Oh No! I think Miguel took it again!". "Who's Miguel?" he asked. "Oh, he's just the troll that lives under my bed" I said.
Well that started it all! I spent the next five minutes convincing him that there really was a troll that lived under my bed!! I said there are two kinds of trolls: Bed trolls and Bridge trolls. You could tell that he kind of doubted me but that he wasn't sure. So we both leaned over the bed calling "Miguel, Miguel!". "He must be shy" I said.
Hadassah, who came to join the conversation, told me that She in fact ALSO has a troll living under her bed! But her troll is a princess troll with curly hair and eats her toys!!
After a while of painting the tale of these trolls I left the room. When I returned River hands me my phone and says (very seriously) "I got your phone back, but Miguel bit me!!". He showed me his hand and on it were two teeth marks!!!
