Really like the fun colors.
#75 the peeps font is too thin, which may be one reason I suspect you outlined the whole logotype in #76 and #77. The outline may be a good thing, but can you show a more more substantial (thicker) peeps without outlining the whole logotype to compare to the current?
Why tilt the faces down? Did you play with the fact the faces in the p's look like e's? Can that be exploited some how or is it possibly an inconvenient coincidence that creates more confusion that possible clever integration. I'm think if there is some brainstorm about integrating the p's, e's, and faces in some unique way, could be a very distinctive logo. I don't have any ideas about how to do so, just seems like it may (lower case may) be possible to do so.
