Soon current version of the toy will be deemed unsafe and start catching fire. You'll have to get a new version of the toy, still available easily but it'll only run on crazy expensive batteries you can get from Vicky. Or you could try to build your own batteries but specifications for those are hazardous, undocumented and changes over time.

Also, for the new version of the toy you'll have to learn to play a new game as the old way to play with it'll become half-working.

At least that's what parents are afraid of.
