|Jake making a prism-gram|
|Introduced in||"Her Parents"|
The Prism-gram is a prism-like object that sends mail in the Land of Ooo, and possibly comes from the Crystal Dimension. Once one has written a letter, one swipes the Prism-gram on the paper and it absorbs the writing. The message is transformed into light waves and sent to another Prism-gram via a beam of colored light. Then it converts the letters into brain waves and shoots them onto one's forehead through a similar, laser-like beam. So far, it has only appeared in the season 2 episode "Her Parents," where Jake used it to send a message to Lady Rainicorn's parents, Bob Rainicorn and Ethel Rainicorn.
- It seems that it can really hurt once the letter (in the form of a laser) is shot at the forehead.
- The letter Jake wrote means: "To Mr. Rainicorn and Mrs. Rainicorn, Rainroad 47. Please come here one hour early for lunch. I don't have a pet turtle. From Jake." In Korean, it reads: "무지개콘 선생님과 사모님께, 47 무지개 길. 점심에 한시간 일찍 와주세요. 나는 애완 거북이가 없어요. 제이크 드림"
- An exact translation is: "Rainbow cone teacher and ask her, 47 rainbow road. Lunch an hour early and I do not have a pet turtle. Sincerely yours, Jake."
- The Prism-gram appears very similar to a "Common Soul Gem" from the Elder Scrolls series. It also resembles a "Soul Fragment" from a minigame in the MMORPG RuneScape.
