Goof Troop: Have Yourself a Goofy Little Christmas (1993)
That means it has the strengths of the series: family stories, told with heart, with the occasional very funny line. That also means it has the weaknesses that plagued the series: unrelenting ill luck that isn't actually funny, and an awkward mesh between the character based humor and the over-the-top slapstick.
There is also a certain level of unexplained zaniness and a few really confusing cuts that made me wonder if the episode was cut down from a slightly longer special. The ending, for example, seems to come out of nowhere and makes no sense. I couldn't find any information about it, though. It could easily just be poor writing.
Have Yourself a Goofy Little Christmas gets an A for effort and a C- for execution. Skip it, unless you have super-fond memories of the show.
