Boomseeds are similar to the Chomper Plants. They can trap Phantoms too, as well as the King Phantom. They are found in Adventures where there is a pile of boomseeds. Boomseeds are first introduced in the Meet Cosmo Adventure. Boomseeds were made by Cosmo to protect Jamaa from the Phantoms. To trap them, you need to get some boomseeds and then put it where the phantom is, and then in a few seconds it will be trapped. Boomseeds are made out of honey, nectar, vegetables, fruit and the boomseeds. However, it has been said Chomper Plants have been used more often than Boomseeds. It takes up a lot of Boomseeds to defeat the Phantom King!
