OOMPA-LOOMPAS

An object that identifies the Oompa-Loompas is the hammer because it represents the hard work of all of them.  Another object which identifies the Oompa-Loompas is the cacao beans because they love eating chocolate.  The last object is the microphone because they like singing.

Firstly, the Oompa-Loompas are energetic because they work all day long, they sing and they dance.  Secondly, they are hard-working because they work a lot.  Moreover, they are clever because they make fantastic machines.  They are shy because they speak with gestures.  They are obedient because they do what Mr. Wonka asks them to do.
