I fixed the Plants Alive
page.. no idea how we ended up with penguin defense information in there. Thanks for letting us know!
For all of the bixie defense games, I personally use druid towers (the blue ones, I believe) with a slowing bixie (honey bixie?) paired up nearby.
For Honey, I'm Home... if I recall correctly, I ended up putting a druid down in the bottom center (on the grass above the entrance.. this one was upgraded always first), with a honey bixie to his left and across on the right grass patch.... one on the grass above him, to catch stragglers that make it to the hive (this one wasn't upgraded quite as much)... one near the upper-left corner with a honey bixie nearby, not on the top row of grass, but the row beneath that (can catch them on three paths that way).... and one over on the right middle, with a honey bixie nearby, to catch waves that take the long path.
I really don't recall We've Come for the Honey very well. My advice, in general with bixie defense, is make sure you have one druid and one honey bixie near each entrance, and a safety net of a bixie near the hive. It doesn't work perfectly every time, but upgrades and having frequented paths covered is highly important. Adjust bixies around if you fail and need to do it again based on patterns that you saw with their movements. :)
I failed at bixie defense way too many times, so don't feel bad.. it's tough! :)
