The junk items that are worth the most are found in Garnet Weald and Amber Wilds, they are generally Truffles and Gems that can be found in the river or on the sand. In Amber Wilds you can also find coins on the sand too, even Silver ones sometimes. Thunder Shards are quite rare, they are used to make lighting furniture and are formed when a lightning strikes the road during rainy weather.
The Bunny character is there mostly to divert hits away from you or to act as decoy and lead enemies away when attacked by enemies at night. Damage scales quite significantly with the Strength stat so if yours is low you wont be able to deal any. There is no sexual content locked behind battles though as all the sex scenes only happen when you lose to monster girls (for now).
I do plan to let you walk over the planted stuff on your farm, it is on my to do list! Though I am not sure I can make the Trees seethrough. I Also plan to make the seedable area more visible in the future, though at the moment I haven't quite decided on the best way to approach that issue yet.
Thank you for your comment, and your tone was not harsh at all :)
