S4·E8 I want to be all right all the time

The pups are at kindergarten, playing with plasticine. Tessa has made a figurine, but it won’t stand up. Tip gives her some advice and she fixes it. Tip is happy, and spends the rest of the day convinced he’s always right. But the afternoon has some surprises in store: he’ll soon realise he can’t be right all the time, and he doesn’t want to be, either!
