Ehh, I am the 1st to cross thinger, we just need to hope that the 2nd trailer of this movie will show us more footages of Ruby and Chomper.
And, looking carefully the 2 in the trailer, Ruby seems younger and also Chomper, as he has not his chest muscles. And, tha lake... reminds me... Ruby's home! When she washed durin' her star-day celebration!
