Toys:

Best: Encore. 'nuff said.
Worst: Encore. Not enough of them. And no shockwave, jetfire, predaking, combiners bar bruticus.

Events:

Best: The ones we had and stealth transforming Griffins' TFs into alt mode.
Worst: The ones we didn't have and missing out on transforming Griffins' TFs into alt mode.

But seriously, the only thing that will remind me of 2009 as a year, is when I look at my spreadsheets and see the year of aquisition listed for the encore toys I got this year.
