From the Super Mario Wiki
The Chuboomba is an enemy found in Mario & Luigi: Bowser's Inside Story. Their name is a portmanteau of "chubby" and "Goomba". Chuboombas are large Goombas holding lollipops, and are encountered at Cavi Cape and Plack Beach.
Chuboombas are fought by Bowser in the overworld, and are the first (and weakest) normal enemy he encounters. In battle, it attacks by tackling Bowser, which he must counter with a punch. If it wheezes before tackling, it will hesitate before impact, so the player must remain alert. If Bowser inhales the lollipop, he will recover 20 HP, and the Chuboomba will run away crying, defeating it (though no experience is given).
Chuboombas are always the target for the demo of Bowser's Special Attacks. Unless the player gets an "Excellent" during the attack, the Chuboomba will not die and instead run away.

- Despite being a Goomba, the Chuboomba is not a member of the Koopa Troop; however, it may be possible that they were brainwashed by Fawful, like most of the Koopa Troop.
- Chuboomba is similar to the boss, Shrooboid Brat from Mario & Luigi: Partners in Time; both are fat enemies that have hard time walking due to their weight, and both carry lollipops.
- The lollipops look similar to Jelly Pops from Paper Mario.
- The top screen of Bowser's Special Attack demos/tutorials always show a Chuboomba being defeated by the acquired Special Attack without the lollipop, which is normally impossible, since a Chuboomba without a lollipop usually no longer fights.
