For creating short cartoon comedy skits, I recommend using Canva. It's an online graphic design tool with a user-friendly platform and a drag-and-drop feature. It also has a suite of AI-powered design tools, including Magic Media, which can generate short videos from text-based prompts or an existing image.

To generate audio for these skits, you can use ElevenLabs. It's a voice AI tool that allows you to create or clone voices in up to 30 languages. It can turn written lessons into spoken words, making it perfect for creating audio for your skits.
