In my opinion there were several awkward moments with Tippy, the little stegosaurs in LBT 8, in which he reminded me very much of a Teletubby. In the German version of LBT 7 Cera uses a hardly translateable term to describe the smell of the volcanic spring (in the English version she says eggstealer breath) which also sounded kind of awkward.
I need to watch some sequels again, but these are the moments that come to my mind. Which are yours?
