The latest episode of Goseiger featured a pretty funny concept: what if one of our heroes couldn't power down and transform back? This happened to Alata - and naturally comedy ensued.
There was a new ending as well, featuring the Goseigers using these microphone toys. Those items don't appear in the show. This series has been very heavy in product placement, from cards to Headers. Not complaining, really, but it is the first time I've seen a prominent item sold but not used in the series (they usually try to find some way to squeeze toy-features into one of the episodes) Just a curious change of pace.
BTW, you might notice an image (below) of GoseiPink and Yellow together. That's from the preview of episode 9, which they preview at the end of the episode every week. Usually the previews aren't that great for screen shots, as it has text over the images - but for the past two weeks I've been able to get some cool images from the last seconds of the preview, when the text goes away.
