Lilypad Token

Lily Raft. This token made from emerald gemstone floats on water. When you throw this token into water and speak a command word while it is floating, it turns into a giant lilypad raft. The lilypad is 10ft. in diameter and can hold up to five medium sized creatures.   The creature who spoke the command word can use a bonus action to command it to float towards a direction. The raft does so at speed of 30ft. per round until it reaches its destination or is commanded to stop.   Repeating the first command word turns the raft back into a token provided that no creatures are aboard.
