I want additional emojis for my Note II. What is the best / easiest app to obtain them?

I want additional emoticons for my Note II. The only ones that came with the phone are a few green Android guys, but I need a lot more! Research has revealed to me that the Note II is the most difficult to download apps that actually work on the phone. I would prefer not to have to access an entire emoji keyboard, just to insert an emoticon into a text message -- anybody have a solution for me?  Thanks in advance for any advise
