Where is my elemental? – Slugterra: Slug it Out 2 Review

I bought my son one of the Elemental Slug packs and it said guaranteed new slug.. well, he got tons of gems and no slug. What a waste of money. Now I have an upset 8 year old and no way of solving this issue. I will not be putting any more of my money into this game.
