Query: USE THE RIGHT BATTERIES!!!

My husband got this ready to put out on christmas morning and we put regular heavy duty batteries in it not thinking anything, and he showed me all it could do, well when it tried to walk it would just wobble back and forth. I was verrrry disappointed needless to say!! Then it donned on me that it might need stonger batteries, so I put in some alkaline, and imagine my happyness,, it was running and walking, doing everything they said it would with no problem, can't wait for my 5 yr old to see it on christmas morning!!! Happy Holidays, I hope this helps some of you disgruntled parents out there, it is not a waste of money, just invest in good batteries.
