I used to watch these movies when I was a kid and I haven't figured out the names and I've been thinking about them on and off for a couple years. I think there 90's movies the first one is part real and part cartoon. It was about a kid that rock climbed and he had a blonde little cartoon friend with like a purple shirt. And something bad happens??

And the other is about dogs I think and there was a BIg black and white one that sang an oldies song at one point and I rememeber to security guards and one was eating jerky or sticks of gum.

The second one MIGHT be Oliver and Company?
