This Marvelous Baby Groot Cake Topper was made by Sugar & Spice Cakes. He is the only one small enough to carry the bomb detonator to the correct location and push the button to start the 5 minute timer.
It is humorous when he keeps reaching for the button the will instantly explode the bomb as Rocket tells him what switches and buttons to push. The scene ends with Groot running off to where he’s supposed to go and Rocket saying, We're all gonna die.
Groot as a young child adds a nice comic relief to this movie. Groot is an amazing character.
He was made using modeling chocolate. The baker has a video tutorial for sale on her site that shows how she made him.
