When the sisters are chasing after Chelsea in the sleigh with the puppy they come across some ice. Right after Barbie and Skipper run over it they slip a short distance away from the edge and fall on their backs stopping right away.
In the next shot they're shown as being farther away from where they slipped and there's now a hockey net behind Barbie that wasn't in sight before.
The battle-bots reboot is on the TV but the show was not rebooted until 2015.
