My Nintendo DS

My DS goes ding ding! When I turn it on
And goes... when I turn it off
Part of me (mentally)
As red a rose
My best friend!
Mine for the last few years
A big ‘M’ on the front
It has eight red buttons
In perfect condition
There are plenty of games
There’s always something to play
So many things to discover
Many journeys to travel
My brain can’t hold all this knowledge
Only my Nintendo can.
