A link to a snippet of a movie.
A movie called Funky Forest: The First Contact (Naisu no mori)
And from the promotional material below, it's neither Funky nor Foresty.
I've seen some films in my time. From Killer Poo to films with killer ants nesting in a nutsack being wanked out to wreak revenge on bullies, culminating in giant spiders raping women in the shower to give birth to Spiderman type offspring. Even that recent anthology trailer with the giant killer spunk rampaging through the city, the gay arse-biting werebears, the Diary Of Anne Frankenstein, and the bumrapey zombies.
But this...
...even with subtitles, this has to be 8 minutes of a whole new level of What The Holy Mary Mother Of Fuck...
