Here's the opening previews to Rock-a-Doodle 1992 VHS:

1. FBI Warning
2. HBO Video logo
3. Advanced Action Wisk promo
4. Thumbelina sneak peek
5. Feature Presentation ident
6. Samuel Goldwyn Home Entertainment logo

NOTE: Yes, Rock-a-Doodle is way too cheesy for an animation fan's liking, so I'm sure it's an awfully low-budget film for Don Bluth. But it's a bit interesting.

DISCLAIMER: I own nothing.
