The Heads on Tails Expansion includes 3 new tail tiles for the Cartoona game. But these are not regular tails, these are little head tails that will allow you to build two-headed creatures! This expansion will also include 3 new cards: Use a tail head as a main head or vice versa +4 to any tail head tile Use a tail head as front or back feet This expansion will allow you to build even wackier creatures, and it also changes the game slightly to make 7 and 8 tile creatures easier to complete.
