I automatically assumed that the boxes contained more Giftos, if the kid said that one Gifto made it the best Christmas ever.
Where is Gifto getting the material? It looks like it hasn't actually used anything as fuel or raw materials, but that's impossible. Is it boxing air? It'd still need boxes.
And Gifto read the inscription on the the first box for the young boy, "Either this box contains an angry frog, or the box with a false inscription contains an angry frog, but not both." and on the second "Either this box contains gold and the box with a false inscription contains an angry frog, or this box contains an angry frog and the box with a true inscription contains gold."
It really was the best Christmas ever :)
Until the frog attacked everyone...
In the holiday spirit, here's a comic that many LWers may appreciate... and perhaps even find useful for illustrating a certain, ah, topic:
