I'm wondering if these aren't as common as I thought 😅
On Easter my church would give the kids their own egg carton and/or plastic eggs (keep in mind I went to a megachurch and they had funding/staff/volunteers for stuff like this lmao) with various items related to the crucifixion in them, the last egg being empty to represent that Jesus is no longer in the tomb and has risen. We'd go through them one by one and talk about what the item represents and what verse it's connected with. It usually goes in order of the crucifixion story and is just an interactive way to get more kids engaged.
There are pre-made kits available online but people also DIY them. And since there are only 12 slots and accessibility of items can be an issue, sometimes the items vary. I don't think we ever had a chicken in ours (representing when Peter denied Jesus), I think it was usually a feather, but sometimes they'd focus on different parts of the story and leave other things out, stuff like that.
But it's like... if you're gonna have things like a whip, or a spear, or nails, or the crown of thorns, even the cross, you have to talk about why they're there and talk about the torture that occurred. That's wild to me in and of itself even without the added "btw remember this is your fault for being so evil :)".
And I know why this is the case, but it's still kinda wild to me that the "sex is dirty, swearing is bad, media is evil, we must be pure and holy" crowd is often sooo desensitized to violence that they don't even think twice about the crucifixion or some of the other stories in the bible being told to their children.
