Some tips from an craftsman: please avoid slotted round bolt, especially big ones. Instead use hex head or hex socket bolts.

It is not a big problem perhaps if the bolt is designed to be a single-use fastener. This might explain why moon rabbits almost never take off their ears/antenna. Or could the ears are simply their shackles as slaves?

一点宫酱的建议：不要用一字的圆头螺丝，尤其是大号的。最好用外六角或者内六角的螺丝头。如果螺丝只是用来一次性固定的话倒是问题不大。这或许解释了为啥月兔们几乎从不拆下自己的耳朵or天线。或者说，其实天线是奴役月兔们的镣铐吗？
