We regret to inform you that Palworld has a smutty lizard 'seeking a night of love' with humans, which raids bases in hordes of 'rampaging fangirls'

pcgamer.com:

Palworld is an edgy game—more in implication than reality. While it's grown a reputation for a Happy Tree Friends-style subversiveness, everything in its world is pretty sanitised. For instance: Pals eat human cadavers, but they just peck at them until they vanish. 

The whole game feels like a send-up of Pokémon's simmering 'it's messed up if you think about it' worldbuilding and Pokédex entries, just more overt. As is the case with Lovander, a pal that explicitly wants to bone down with humans. Lovander is number 69 in the Paldeck, naturally, and its entry reads as follows:

«Seeking a night of love, it is always chasing someone around. At first it only showed interest in other pals, but in recent years humans have become a target of its debauchery.» What's more, these things can raid your base as a pack of fangirls with adjectives ranging from 'bandwagon' to 'rampaging'. Lovander also drops mushrooms, cake, as well as strange and suspicious juices.

Lovander's design, meanwhile, seems to be a pretty obvious parody of Pokémon's Salazzle, which has a cloud of  «poisonous gas» that «contains lots of pheromones that attract male Salandit», the implication being that this lizard is a bit of a perv. I should take this opportunity to warn you that you should not Google «Salazzle» in any capacity. Don't repeat my mistakes.

In terms of what Lovander does, it's all above-board—nothing salacious actually happens in the game world. Despite being a normal-element pal, Lovander's mostly just there to cause you real-life psychic damage. What makes things worse is that it actually seems a pretty viable choice for your base.
