Ben 10 Ultimate Humongusaur Memory
Humongusaur is the strongest alien that Ben got and he is even more stronger once he transformed into ultimate Humongusaur. Sadly, he can't keep that form too long because it consume too much power on his omnitrix. The game might be about Humongusaur, but you are not going to transform into the behemoth as you just need to mix and match things here. Match 10 aliens before your time runs out. You need to remember where you found a certain alien as you are going to go back there once you find the other half. You need to go on and find other matches to finish the level.
