You are possibly thinking of 'cumulo-nimbus' clouds
Clouds are actually categorised into groups based on shape and size. Large puffy clouds are called cumulus or cumulonimbus
The tall puffy clouds that form by vertical motion in warm and humid air are called cumulus clouds. These clouds typically appear isolated, with a flat base and a dome-shaped top. They are often associated with fair weather, but can develop into larger storm clouds if the atmosphere becomes more unstable.
Fluffy cotton-like clouds are called cumulus clouds. These clouds are typically seen on fair weather days and have a distinctive puffy appearance.
You are likely seeing cumulus clouds, which are puffy and often found at higher altitudes. When they form in rows, they are called a "field" of cumulus clouds. These clouds typically indicate fair weather conditions.
They are called "cumulus" clouds, and sometimes are colloquially called "fair weather" clouds.

The low puffy white clouds that can change into cumulonimbus clouds are called cumulus clouds. Cumulus clouds are often associated with fair weather, but can grow into cumulonimbus clouds, which are tall, dense, and produce thunderstorms.
The clouds that are puffy masses formed by vertically rising air are commonly known as thunderheads. These clouds, with the scientific name of cumulonimbus, may produce severe weather such as lightning, hail, and even tornadoes.
they are puffy because water is inside the cloud. They are called cumulus clouds and are formed, like all clouds, of water vapor.
CUMULUS
The tall puffy clouds that form by vertical motion in warm and humid air are called cumulus clouds. These clouds typically appear isolated, with a flat base and a dome-shaped top. They are often associated with fair weather, but can develop into larger storm clouds if the atmosphere becomes more unstable.
In science, "puffy white clouds" are known as cumulus clouds.
Cotton balls-like clouds that are puffy and separate are called cumulus clouds. They are usually associated with fair weather but can grow into bigger storm clouds if conditions are right.
Fluffy cotton-like clouds are called cumulus clouds. These clouds are typically seen on fair weather days and have a distinctive puffy appearance.
Cumulus clouds are thick puffy clouds that occur at middle altitudes, typically between about 2,000 to 20,000 feet. They are often associated with fair weather, but can develop into larger storm clouds known as cumulonimbus clouds.
