I'm sorry, but there seems to be a confusion. "Big Idea" is known for producing the VeggieTales series--an animated series that teaches moral themes based on Christianity. On the other hand, "Mario Party DS" is a video game developed by Nintendo and has no relation to Big Idea or VeggieTales. Additionally, DVDs are video formats, while Mario Party DS is a videogame designed for the Nintendo DS handheld gaming system. With that said, if a fictitious DVD was created that was a crossover between Big Idea's characters and Mario Party DS or an animated adaption of the game with features, it could potentially have the following special features: 1. Behind-the-Scenes Featurette - Making of the Big Idea's Mario Party DS animated crossover - Interviews with the voice actors from VeggieTales and Nintendo's game designers 2. VeggieTales Concept Art and Character Designs - Art galleries that showcase the conceptual crossover between VeggieTales and the characters of Mario Party DS 3. Interactive Game: Veggie Kart Racing - A simple, DVD-menu-based racing game featuring the VeggieTales characters in karts 4. Mario Party Minigame Tutorials - Tutorials teaching how to play some of the mini-games featured in Mario Party DS 5. Sing-Along Songs - VeggieTales versions of classic Mario tunes and original songs with karaoke-style lyrics on-screen 6. "How to Play" Mario Party DS with Larry and Bob - A fun, animated guide on how to play the video game, narrated by VeggieTales characters 7. Veggie Gamer Tips & Tricks - Exclusive tips for mastering Mario Party DS, presented by the characters of VeggieTales 8. Bonus Episode: "The Quest for the Golden Mushroom" - An original VeggieTales story inspired by the adventures in Mario Party DS 9. Deleted Scenes - Animatic and storyboard sequences that didn't make it into the final crossover concept 10. Audio Commentary - Commentary track by the directors and producers discussing the unique challenges and fun moments of creating a crossover between VeggieTales and Mario Party DS Please note that this is purely a fictional and speculative creation of DVD features for a crossover that does not exist. In reality, there are no known Big Idea productions related to Nintendo's Mario Party DS.
