Young Cricket and Master Mantis
From the Super Mario Wiki
Young Cricket and Master Mantis are two characters first appearing in WarioWare: Smooth Moves. They are said to be roaming the world in search of new poses, suggesting that they already know about the Form Baton. When they are first introduced, they appear to be rather serious characters, shown training through tough conditions, but it is then revealed that they "fit in" with the rest of Wario's "friends".
WarioWare: Smooth Moves
Young Cricket and Master Mantis make their debut in WarioWare: Smooth Moves. Their story starts with the two characters being very hungry. They find a place to buy dumplings. Cricket starts running on people's heads to the front of the line. Then the game starts. Every time a microgame is lost, one dumpling is taken by someone. When getting an extra life, a new one is laid on the table. Eventually, Cricket reaches the front of the line, only to be looked down upon by the people he stepped on. He runs on their heads again back to Master Mantis and tells him that they should get in line.
