be more elastic

“even if it’s a snail’s pace”

Like a rubber band,  a snail expands and contracts. 

Movement comes as a result of a rippling of the flat underbody that flexes and

releases tension which pushes the snail forward.

The underbody is made of muscles.

 

Like an old rubber band, a snail is rigid.

Flexibility comes as a result of excretion of silvery slime allowing the snail to

move around corners, upside down, and other situations.

The gravity is defied.

 

Like a discarded rubber band, a snail might be regarded as not good for much.

Movement is slow and appears heavy creating stigma of being lazy. However

trivial, headway is steady.

The weakness is offset by a durable shell.
