HURRAY!
Pumpkin Tomato 'Panga'
This is the playground where tomatoes come to play every day.
They love playing on the see-saw. One day a big pumpkin comes
and sits on one side of the see-saw.  When he does not get up
for a long time, the tomatoes decide to sit on the other side and
lift the pumpkin up so that he falls off.
The little tomatoes start climbing on to the other side...1, 2, 3,
4, 5 ....... 25. Huh! The pumpkin is still sitting and laughing.
So, the big tomatoes decide to help. The little ones get down
and make way for the fat ones. 1, 2, 3, 4 ..... 20.
Yeah! The pumpkin is up in the air. It shouts — Bring me down,
bring me down please!
'Panga' is a colloquial word which gives  the sense of a problem or a quarrel. It has been used
deliberately because children can find it amusing.
