This soft little teddy bear is the stuff of nightmares. Theodore is said to be inhabited by a volatile and vengeful spirit. Others say it is a efreeti in disguise. 

Using an action you can place Teddy on the ground and say the phrase Teddy Boom and the number of feet or amount of time you would like teddy to walk. Teddy will then walk with it's head spinning, the specified distance or time, stop and laugh, then explode. Maximum distance 120ft. Maximum time 21 seconds. Example: Teddy boom 30ft

Alternatively you can say the phrase Theodore Boom Boom and Teddy will start counting out loud down from 5, laughing at 1 and explode. Suggested action would be to toss Teddy at intended target within the countdown time.

Each creature within 5 feet of explode point must succeed on a DC 12 Dexterity saving throw or take 4d6 fire damage.

Due to less wind up time the alternative action only does 3d6 fire damage.

Teddy moves 30 ft per round when walking. Teddy lures enemies within 20ft. On a failed wisdom save of 13
