Another option will be apet rabbit from Weismart's blog

The Basics-All you need for OSRS gold fundamental Archeology in Runescape are the next - Group of NPC Archeologists (Two or more). A group of NPC Archeologist can be obtained by talking to Mrs. Griffith in Varrock museum, original floor. She can loan you a few people for ten excursions for just 10,000GP per year, and you'll be able to purchase a few for 500,000GP to keep with you. Here are the differences.

I got a concept for easter its rather like a tresure trail but remixed in a easter egg hunt you start of by talkin to the easter rabbit and she says oh precious plase helm me YOUR NAME I have a bad cold and easter is caneled intill next tuesday I put out the eggs I need you to go about getting the eggs every time you get an egg crack it open and a choclate rabbit in side will provide you a fresh clue they once youv recieved all of 10 eggs and have busted them u shall return to me and recieve your prize should you need help have this magical chicken egg from last year it will teleport you to the next egg just once.

The prize would be an option a magic ring like the egg ring however this turns you into a bunny like in castle wars you'll still be abble to trade trade but if you do commerce ur ring will come un operate and if your done tradeing u will have to right click you ring and then click function magic rabbit ring the other down side you wont be able to run or perform emotes when its operateing.

Another option will be apet rabbit that if you releace it it will follow you like a kitty it wont grow or must be interacted whith you could do that whith it or weild it and it's going to be craddled in your arms and buy RS gold should you attempt to att it will disapear and when ur done fighting it's going to end up on your arms or stock.
