marriage of Animal Gas x Big Buns, celebrating notes of cookiedough and petrol. Animal Gas: Animal Cookies x (Gorilla Glue #4 x Stardawg) Big Buns: Gorilla Glue #4 x (Big E OG x MAC) Expect pungent plants. Smell and bud structure are pretty much consistent through the phenos, but there are still green, purple and short and tall phenos. My favorite was a tall pheno that grew like animal cookies but had gorilla glue nug structure, purpled up pretty good, and stank like a perfect mix of GG4 and Animal with a hint of new leather.
