made this for my son's 4th birthday. He wanted an army/camo bday party (my dad/brother are both army and my bro is being deployed next week) This was a red velvet cake w/ vanilla bc icing... the "river" is piping gel--the stones are milk duds--the grass is icing--the "dirt" is crushed oreos--i wrote happy birthday on the flags b/c i had no where else to put it! i love the army guy crawling up the side of the cake--all the army guys/tank are plastic--got some great ideas from many photos off this site
