Get Tall for Animals Best Upgrades: A Goal-Based Order for Pen, Burger and Trail

There is no single "best upgrade" in Get Tall for Animals — the right first purchase depends on your goal and on how much cash your animals are earning. For the one goal that solid gameplay evidence actually covers, the early height-and-power climb toward the next zone, the defensible order is simple: buy Burger upgrades first, defer Pen, and leave Trail unranked.

What each upgrade path is for

The game's own description names exactly three upgrade lines — PEN, BURGER and TRAIL — and slots them into the core loop: eating raises your GROW VALUE, growing your legs carries you up to the sky islands, stolen eggs hatch into animals, and animals earn cash for you, including while you're offline. Every upgrade on all three paths is paid for with that same animal-driven cash, so each purchase competes with hatching more animals and growing the income that funds everything else. Our animal income guide covers that side in detail.

What the evidence can and can't compare

Only directional comparisons are currently backed by observed play. Each Burger level raises how much food you eat and how fast you eat it, which converts into more height and power, and the burger you climb visibly gains extra tiers as levels go up. Pen (house) upgrades sit at a much higher price point — the first one that unlocked was quoted in the millions — and at least one purchase visibly changes your fence to a silver tier marker. Trail is the outlier: nothing observed or published attributes any cost or effect to it, so it cannot be ranked against the other two.

Don't trust a ranking that claims more than this. In the session this page is built on, even the players themselves didn't know what a Pen upgrade adds — one guessed it "might be another 1x" (double), and neither could confirm it. Similarly, a small run-speed increase was noticed at one point, but it was never tied to any Trail purchase, so it can't be counted as a Trail benefit. The one hard scale available is progression itself: zone gates at 100 power, 400 (beach), 1,000 (mountain) and roughly 6,500 for the heaven/sky zone — those are power values, not levels, and the final figure was given as approximate. The progression guide and sky islands overview put those zones in context.

The order to follow for the early height and power goal

1. Roll cash into the next Burger level whenever you can afford it. In the observed session, the player upgraded from level 3 to level 4 the moment money was "just enough" and immediately reported eating more food, eating faster, and growing much taller. By upgrade level 7 the burger had stacked to 10 tiers, and at level 11 the player judged themselves ready for floor 3. The pattern held all session: more Burger levels meant more height and power.
2. Skip Pen while it costs millions. That's exactly what the players did — the upgrade unlocked, they saw the price, and went back to cheaper goals first. Buy a Pen level only when it's a small dent in your balance. If you do, watch the fence change as your confirmation that the tier took, not any promised doubling.
3. Treat the gate numbers as your checkpoint. Height and power are means to an end: 100 for zone 2, 400 for the beach, 1,000 for the mountain, around 6,500 for the sky. While you're closing on a gate, keeping the Burger levels coming is the evidence-backed move; hoarding for an expensive Pen purchase slows the climb.
4. Fund the rolls instead of waiting. Animals keep earning while you're offline, and more animals mean faster rolls through every step above — see how to get cash fast if income is the bottleneck.

When the order changes — and what's still unknown

This Burger-first, defer-Pen pattern comes from one early-game session aimed squarely at height and power, and it isn't shown to hold at every stage or for every objective. Pen may well become worth buying once its price is trivial next to your cash rate, whatever the size of its power gain turns out to be. Trail might serve a completely different purpose — speed or egg-theft movement, for instance — but with no attributed cost or effect anywhere, the honest position is to check what its menu offers in game before spending on it rather than trusting any published ranking. And because update patches can change costs, payouts and upgrade effects, re-check prices in game before a large purchase; any fixed price table you find online should be treated with the same suspicion. Active codes can top up your balance between purchases, but they're a bonus on top of the animal income that really pays for upgrades — for the height side of the goal itself, see how to grow taller.
