Here's my suggestion for the English translation:
The Easter Bunny in Carcassonne
At Easter, old practices have survived in Carcassonne: As a sign of fertility, the Easter Bunny delivers coloured eggs that you find in their nests.
Extra pieces
22 new landscape tiles (10 with Easter egg nest and 12 with Easter bunny)
1 Easter bunny figure
A lot of Easter eggs made from chocolate
1 die - with 6 sides - 2 sides each with 1, 2, 3 (example: die from the mini expansion "The Flier")
Expansion rules
Overview
The Easter Bunny hops across the land delivering his Easter eggs. Players attempt to collect Easter eggs by completing features or finding them on farms at the end of the game. The Easter egg nest is completed like a cloister and also yields Easter eggs. The Easter eggs are worth points at the end of the game.
Preparation
This expansion is intended to be played with the base game and any expansions. The 22 new landscape tiles are to be mixed in with the other landscape tiles. Keep the supply of Easter eggs, the Easter Bunny, and the die in a nearby general supply area.
Game rules
The new tiles are placed according to the normal rules of the game.
Tile with Easter Egg Nest
Tile with Easter Bunny (The player immediately places the Easter Bunny on the tile.)
The Easter Egg Nest
When a player completes the nine-tile grid surrounding a nest, the Easter Egg Nest is scored after the regular scoring-phase for the turn. It may be that a nest tile fills a hole and scores instantly.
In this scoring phase, the player completing the Easter Egg Nest earns 2 eggs. All players get 1 egg for each one of his or her followers on the nine-tile grid.
When an Easter Bunny tile is placed the Bunny figure must be immediately placed on the tile. If it is not currently on the board, then it is moved there from the storage area. If it is currently on the board, then it is picked up and moved to the just placed Easter-Bunny tile. While on the board, the bunny is not on any particular feature. The bunny is a neutral figure and his placement is in addition to any wood move.
The placement of an Easter Bunny tile triggers the movement of the Easter Bunny. The current player shall take his normal turn including moving wood and scoring. Followers may be deployed on the tile on the regular features but may not be deployed on the bunny icon. After scoring for the turn is resolved, the bunny's movement is resolved. Thereafter the next player in turn order takes his turn.
The movement of the Easter Bunny
Starting with the current player, all players in turn order roll the die and move the Bunny as many tiles (hops) as indicated by the result of the die roll. The bunny hops from tile to tile orthogonally and may not hop diagonally.
The Bunny may sidestep, and he may hop in more than one direction on a single move. He may not hop on the tile that he started from. He may not hop on places where no tile has been placed. It is possible for the bunny to get caught in a dead-end situation as he may not be able to backtrack on certain tiles during the move. In such a case the bunny movement round ends there. If the Bunny hops on a tile with at least one follower, the players get one Easter egg for every follower on that tile; the followers remain on the tile.
Final scoring
In the final scoring, there are no eggs given for followers on the nine-tile grid surrounding an Easter Egg Nest. The Easter Bunny has no effect on final scoring.
The player with the most eggs gets 10 points, the player with second most gets 5 points. If there is a tie, all players with the same number of eggs get the points.
Warning!!!: Only Easter eggs not eaten are counted for the final scoring.
After the final scoring all eggs shall be eaten at one's own risk.
Adaptation: If you don't own the die from the Mini-Expansion "The Flier," we recommend ordering it soon.
Also you could use a regular six-sided die and give the Bunny 1 hop at the result of 1 and 2, 2 hops at the result of 3 and 4 and 3 hops at the result of 5 and 6.
Interaction with other expansions
1st Expansion "Inns & Cathedrals"
The Big Follower simply gets one egg.
2nd Expansion "Traders & Builders"
The Builder and the Pig don't get an egg.
3rd Expansion "The Princess & the Dragon"
The Dragon eats the Bunny (the dragon would not miss out on Bunny). The Bunny and the Fairy may be placed on the same tile. If the nine-tile grid surrounding an Easter Egg Nest is completed with a Dragon tile, the scoring of the Easter Egg Nest is after the Dragon movement.
4th Expansion "The Tower"
The Tower cannot take the Bunny prisoner. A follower on a tower also gets an egg.
5th Expansion "Abbey & Mayor"
The Wagon and the Mayor get an egg, the Barn doesn't get one.
6th Expansion "Count, King & Robber"
A follower cannot be taken from the City of Carcassonne for the scoring of an Easter Egg Nest. A Heretic on a shrine gets an egg, too.
7th Expansion "The Catapult"
If the nine-tile grid surrounding an Easter Egg Nest is completed with an Catapult tile, the scoring of the Easter Egg Nest is after the Catapult round.
8th Expansion "Bridges, Castles & Bazaars"
A follower on a bridge gets one egg, too. Completing an Easter Egg Nest doesn't trigger the scoring for a castle. The Bazaar round follows the scoring of an Easter Egg Nest, if it was completed by a bazaar tile.
9th Expansion "Hills & Sheep"
Although he is not a follower, the shepherd gets an egg! Hills and vineyards do not affect the distribution of eggs.
Mini 4 "The Gold Mines"
The completion of an Easter Egg Nest doesn't trigger the distribution of Gold.
Mini 5 "Mage & Witch"
The Mage and Witch don't affect the distribution of eggs, and the Bunny may stand with one of them on the same tile.
