'' >The Witches are also striking, because one appears on the poster. The truth is that they could be Sarabeth or Vanessa ... ''

But that would be strange considering that multiple identical witches appear in the the trailer.

>''A green creature in the trailer can be easily deduced as the Swamp Monster, but its appearance is different. It has crab arms and is not covered with moss.''

Could it be The Mirror Crab from Ghost in the Mirror?
