Don't remember where the red crayons are but I know the dark woods come from the creepy
looking dead trees. Same trees that produce the thorns.

yh, where are the red crayons, im stuck 2!

red crayons are in the desert ina cave, you need to brake something (wood i think) its
under a spot where you can put just one house and over a bit are some trees but it's under
a cliff kind of thing? hope that helps im bad at directions

by the way you also get pink crayons and timmy dolls and a girl doll as well

dark wood is found on trees with roses and flowers like that (yellow and purple flowers)

which cave is it? the one with all the bats and tombstones or the one with the spade,
club, heats and diamond trees inside :S
