I really need help finding an old kids movie, here's what we remember.

A dragon crashes into a kids playhouse and eats catfood with knitting needles. He takes one of his scale and puts it into a bucket of water to create a portal.
I think there was also a talking cat and dog and maybe a talking tree at the end. We're pretty sure it was from around the 90's. It was a live action/CGI type movie. The kids *may* have had australian accents but we can't really remember.
Again any help is very much appreciated, thank you
