Trap tricked his family because he was not having fun but I think it is not nice to trick anybody because someone can be finishing a very difficult job.
I think that copying someone is not nice because it makes other people be confused. If I were Geornimo, I would never like that ever like the real Geronimo.
I think Monkeyfur and other genius villagers because like pyramids, they thought the other people will take the precious ruby. If I was Monkeyfur, I would do like her, too.
If I was trapped like Geronimo with polar bear's hand like on the book first page, I would have been scared, too! But I don't know what will Thea do when she is in the same situation.
