Beetlemunchers resemble tadpoles, and as its name suggests, it eats beetles. They rely on Guppycrunchers for their food, the beetles. In Adventure Mode, you can buy a Beetlemuncher for $2000 in Tank 3. They drop pearls (amount needed to be confirmed) that is probably worth more than Niko's pearls. In Virtual Tank, occasionally there will be a Beetlemuncher on sale for 3500 shells. They will drop green shells worth only 10 shells.
