This short video about one little boy and his cardboard arcade is guaranteed to tug at your heart strings and help restore your faith in humanity.

A 9 year old boy – who built an elaborate cardboard arcade inside his dad’s used auto part store – is about to have the best day of his life.

Looks like Purple Panda failed to make the transiton to live appearances.

It was a day probably not unlike any other at children’s day care the Pennsylvania Center in the Woods when popular US children’s entertainer and TV personality David Newell, AKA Mr McFeely, turned up for a visit.

Initially the children appear excited at the prospect of meeting Mr McFeely’s special guest Purple Panda, even calling out the creature’s name in delight.

Things got ugly however, when Purple Panda walked into room of gathered toddlers.

The reaction from the children is one of swift and abject terror, with kids huddling together in fear before fleeing off camera screaming and crying.

Lemons - They’re an acquired taste. It’ll give you a sour face and make kids look hilarious but my wife swears that a glass of ice-tea just isn’t the same without it.
