Consider gifting your friend a personalized piece of artwork depicting her/his favorite cryptid, such as Bigfoot or the Loch Ness Monster. You could commission a professional artist to create the piece, or even create it yourself if you are artistically inclined. Another gift idea would be a book about the history and mythology behind cryptozoology, or a subscription to a magazine about cryptids. A framed print of a vintage cryptozoology illustration could also make for a unique and interesting gift. Finally, you could consider a piece of jewelry or clothing featuring their favorite cryptid or a related symbol, as a nod to your friend's interest in the topic.
Or you can get her/him a star map with the date of the wedding.
