"You have found a blood red egg with a bone white symbol of a cleaver on it."
When this egg shatters, the whole party is transported to a room of the Cleaves. It is generally one room, with one monster, treasure, trap, and special discoveries. When any member of the party leaves the room they reappear back where they vanished from. When the entire party has returned home, the cards are reshuffled back into their decks.
If, when the egg shatters, the party is in combat, the foes will be transported as well. The treasure and special discovery will be protected by the trap and monster.
When Possible rule: If something will not fit in the room, it will not be transported.
For the Cleaves holiday booster pack, here's a monster card.
E1. Easter Bunny
This seemingly normal bunny can be acquired as a replacement familiar, or just as a pet. In any case, you feed it and it will stay with you. This one is white with brown spots, one of which is around it's left eye. It has 1-4 hit points and damage reduction 1/silver. While it's bite does 1-4 and it can kick for a like amount of subdual, it only eats plants. In some ways it's strange.
Once a day it will lay an egg.
1: Plastic egg with 10 assorted jelly beans in it. All otherwise normal.
2: Spun sugar peep show egg. You view through a lense of minute seeing a scene from the movie Easter Parade. The scene plays in an endless loop on a tiny quartz screen where they sing the title song. The lens is reusable though you might have to wait till you have 2. The sugar is edible. The quartz can be left behind or wrapped in lots of cloth to muffle the song.
3: A hard boiled egg, painted with food colors in a traditional zig zag pattern.
4: It looks like a Faberge egg made of copper and set with ornamental gems. When the hidden catch is pressed(disable device 15) a baby Easter Bunny is inside. It will quickly outgrow it's egg and after a month it will be just like it's parent.
5: Foil wrapped chocolate egg filled with yellow fondant.
6: This plastic egg has a 10 foot wide spherical space inside the larger half. This space is originally full of marshmallow peeps.
7: like 6 but contains a fancy Easter bonnet.
8: Like 6 but it contains a large chocolate bunny in a cardboard box with a cellophane window.
Once a year it will transform into a humanoid bunny and deliver Easter baskets to everyone it knows of, in the middle of the night, while they sleep. In humanoid form it has 3D6 hits and damage reduction 10/silver.
But... what does the fancy Easter bonnet do?
It makes you be the fairest lady in the Easter parade. :p
In other words, it's mundane.
I was just padding the random chart to keep the Cleaves from being flooded with Easter bunny swarms.
