Alien Babies! (DWA 348 comic story)
From Tardis Wiki, the free Doctor Who reference
The thirty-sixth instalment of Alien Babies! was printed in DWA 348.
Summary
The babies are all playing in a swimming pool, except, as Eldast points out, for Simon, who is electronic and would zap everybody in the pool if he got into the water. Suddenly, a sea monster rises from the water and traps the babies with its tentacles. After they call him for help, Simon jumps into the pool and zaps the monster (and everyone else in the process), defeating it. Simon is left to play in the now-electrified pool by himself, now that it's no longer safe for the others.
