It's also known to be very dark, even when it's sunny outside, possibly since the trees are so tall and thick that they block the sunlight. The forest is bigger than it looks from the outside, and is also easy to get lost in.
It is home to a variety of creepy plants and animals - there are trees with snarling faces, monstrous squirrels, horrific chicken-deer hybrids, and possibly a lot more that Gumball and Darwin were fortunate enough to avoid.
It was featured in "The Picnic," where Gumball and Darwin got lost inside of it after not following Miss Simian's directions on a field trip. It is also featured very briefly in "The Bet," "The World," "The Shell," "The Question" and "The Romantic."
It is also the location where Richard Watterson sings the original songs from Disney's 19th feature-length animated film, The Jungle Book, from the anthology film (with Richard Watterson as your host), The Amazing World of Gumball: The Amazing Jungle Book.
