Bosses that require buildings or traps to complete

[Yaycub]

I would like to see bosses that are large enough to require base building traps or fortifications to help defeat such as a snake in a garden or a squirrel in the tree for instance. Potentially having to funnel the animal into a dead fall trap that requires hundreds of pebblets or something that the boss must trigger to be damaged as our weapons are too insignificant to defeat.

The Koi fish and the bird could potentially serve as bosses like this as well where we need to have the animal consume bait that we've laced with spider venom In order to begin doing damage to them ultimately felling them using nets/traps/ballista styled building weapons and proper planning.

I could see a situation where we have to run down the raven constantly feeding it venom laced grubs in order to get a huge payout while protecting ourselves from being harried by its attacks by retreating into mushroom bunkers we've placed around the combat area until the venom works its magic like a survival timer.
