Ragnar, the girl turning into the dog bone is from Secret Adventures, which is this really incredible/horrid 90s vaguely (VERY vaguely) Christian kids show
It has a really bizarre horrible CG toaster in it too. This is one of those VHS tapes I picked up at a thrift store b/c it looked like peak 90s forgotten TV and I'm kind of surprised that I recognized it just from that clip of the girl morphing into a bone.
