The two title characters are nude pretty much all the time. Tom (Neil Stubbs, 10) and Lola (Mélodie Collin, 10) have spent the night wandering through the hospital. They realize how late it is and race back to their bubbles before they are discovered. They race into each others arms and kiss passionately.
On the way home from school, at the first half of the movie, the six children stop to go skinny dipping. One boy and 2 girls are seen nude from the rear in this brief scene.
