For my layout, I used the following cartridges: Birthday Bash for the elephants, banner, birthday hats and balloons, Stamping for the words, Doodlecharms for the sun, and then Gypsy Wanderings for the scalloped photo mats.

Close up of the elephants. I welded the bases of the elephants together with my gypsy along with the balloons and string. And then I welded the birthday hats to the top layer of the two larger elephants. The white dot on the balloons are extras from the top of the birthday hats.
