Having recently got one of my all-time favourite films 'Who Framed Roger Rabbit' on DVD, all three Roger Rabbit shorts were included as bonuses. And what great bonuses they were, thoroughly enjoyable in their own way, go perfectly with the film and almost as good.The final Roger Rabbit short 'Trail Mix Up' (sad that there wasn't more) is perhaps my least favourite of the three, despite its more expansive setting and like 'Roller Coaster Rabbit' being closer to the wild manic spirit of 'Who Framed Roger Rabbit' than 'Tummy Trouble'. It is still however very, very good indeed, with its only mark against it being that all the gags in the other two cartoons worked whereas the ending falls flat a little. The basic story is not that special, if you remember the hilarious made-up short that started 'Who Framed Roger Rabbit' you have the basic story structure for all three Roger Rabbit cartoons except in different settings.What stops things from being predictable, repetitive and tired is the increasingly intensely frenetic physical comedy/violence (Roger always getting the worst of it), the wonderfully relentlessly madcap pacing that reminds one of a slightly faster paced Tex Avery cartoon (while occasionally feeling a touch rushed) and writing that's never less than very amusing and at its best hysterical (like with the tree, the numerous Roger Rabbits and the bear).Anybody familiar with 'Animaniacs', 'Pinky and the Brain' and 'Tiny Toons', or who grew up with them, and only saw the Roger Rabbit cartoons recently like me, will love the vibrancy of the colours, the detail of the backgrounds and fluidity of the movements in 'Trail Mix Up'. The music is rousing and energetically orchestrated, Roger and Baby Herman work wonders together and the voice acting is fine. Jessica Rabbit of all the three cartoons is also at her sexiest.Overall, very, very good final Roger Rabbit cartoon. 9/10 Bethany Cox

WITH THIS THE third ROGER RABBIT short subject, there is both a familiarity and new ground covered. Whereas the setting had changed from an urban landscape to the great outdoors, the situational storytelling and gags were by now routine.OUR STORY OPENS with some great sweeping, panoramic shots of what looks like a combination of the Grand Canyon and Yellowstone Park. The depth of the shots is reminiscent of those earlier Disney animated films that made use of the Multi-Plane Camera; which rendered a near 3 Dimensional appearance. The flora and fauna portrayed are colorful, lively and definitely non-anthropomorphic.WE FIND THAT the unseen (except for lower legs)Mother, Baby Herman and Roger Rabbit are arriving at the "Yellowstain" National Park on a vacation camping trip. As is the usual plot device, Mother has to go somewhere and leaves Herman in Roger's charge. Baby innocently follows various birds, animals and insects; leading him into the old saw mill.WITH THE GRAND finale, we have our guys shot through the air and colliding with the carved side of the Mount Rushmore memorial. The faces of Washington, Lincoln, Jefferson and Teddy Roosevelt react in typical cartoon style; making them perhaps the first anthropomorphic rocks in cartoon history.AS HAD BECOME the custom, TRAIL MIX UP boasts of cameo appearances by both Jessica Rabbit (Mrs. Roger) and MGM Cartoon star, Droopy; whose scenes in the ROGER RABBIT Feature were so well received.ALTHOUGH WE ARE somewhat critical of the repetitive and monotonous application of the same situational gag lead-ins, the overall effect of these new ROGER RABBIT Cartoons was very pleasing. It is a shame that the project didn't continue or be revived; as that could well lead to an all out revival of the theatrical cartoons being produced anew.

Baby Herman causes trouble for Roger Rabbit again when he wanders off into the woods whilst on a picnic. All manner of craziness ensues.I'm not the biggest fan of the Roger Rabbit shorts, finding Roger's voice a little on the irritating side and the relentlessly madcap nature and breakneck speed of the action, something akin to Tex Avery on speed, just a touch too excessive for my taste (I had the same problem with Spielberg's equally insane Animaniacs).Even though Trail Mix-Up doesn't rate as highly with me as it does with other reviewers here on IMDb, I still recommend it if only for the fact that pneumatic Jessica Rabbit appears wearing a sexy park ranger's uniform (cue wolf-whistles, leg thumping on table, jaw hitting the floor, eyes popping out, and steam erupting from ears!).(Please excuse the fact that all the reviews I have written for the Roger Rabbit shorts are almost identical—since all three cartoons follow exactly the same formula, I thought I would save myself some time!)

After the wonderful film WHO FRAMED ROGER RABBIT, Disney Pictures experimented by making several short cartoons starring Roger Rabbit and they were shown before feature films--much like the original purpose of classic Warner Brothers, MGM and Disney toons. Unfortunately, Disney also chose to pair these amazing shorts with some of the worst films of the era--virtually guaranteeing they would never see the light of day! Today, the only way you can see them is on an out of print videotape entitled "THE BEST OF ROGER RABBIT". It is NOT available on DVD nor does it appear it will be.In this short, Roger in the great outdoors and as usual, he's watching the troublesome Baby Herman. And, as usual, Baby Herman manages to get into a ton of trouble--leading to an amazing finale! You just have to see it to believe it.Now as to the quality of this cartoon, it is amazingly violent and insane--even more so than the typical Tex Avery cartoon of the 1950s. Because the characters are so funny, the animation quality so superb and the action so intense, this is one of the greatest cartoon shorts you can find---period. Too bad the powers that be at Disney were idiots who didn't realize they had gold on their hands!UPDATE 2/09--According to IMDb "This animated short can be found on the Who Framed Roger Rabbit (1988) Vista Series DVD, released in 2003".
