Yes, it's yet another use of emotional blackmail, junk sentiment and bowlderised reality to make mothers give in whenever their mewling little shits demand sugar-coated, processed crap. O a promo for a yummy milkshake - you may delete according to taste.
But what stands out is the almost rasping, laboured voice of the Nesquik bunny. He sounds like Joe Pasquale with severe constipation. Or like he's terminally ill, the corporate mascot recording his final poignant work even as they read the Last Rites and the hospice nurse inserts a rubber tube up his bottom.
"They only grow up once!" he gasps as his lungs collapse and his pupils dilate. It's the sort of thing an old nanna in Eastenders says to her estranged daughter just before she dies during the harrowing Xmas special, where Little Mo is later ripped apart by Yuletide weasels.
Maybe this is deliberate? You can imagine the conversation. "Mummy, why does the rabbit sound so unwell?" "Just drink your Nesquik, darling, and maybe he'll get better..." Mission accomplished, at least for the milkshake peddlers.
